QUESTION
I have a service running on my linux machine that reads data stored in a .json file when the machine is booting. The service then validates the incoming JSON data and modifies specific system configurations according to the data. The service is written in C++ and for the validation im using https://github.com/pboettch/json-schema-validator.
In development it was easy to modify the JSON schema and just adapt the data manually. I've started to use semantic versioning for my JSON schema and included it the following way:

Answered 2022-Jan-27 at 09:29What you're asking for is something which will need to make assumptions to work.
This is an age old problem and similar for databases. You can have schema migrations generated with many simple changes, but this is not viable if you wish to translate existing data automatically too.
Let's look at a basic example. You rename a field. How would a tool know you've renamed a field vs removed an old one and added a new one? It essentially, cannot.
So, you need to write your migrations by hand.
You could use JSON transformation tools like jq or fx to create migration scripts without writing it in code, which may or may not be preferable. (jq has a steeper learning curve but it's also very powerful.)
QUESTION
I just wrote my first JSON schemas, great! However, I am now looking at how to structure multiple JSON schemas, both during development and later how to host them. There seems to be very limited guidance on this.
Of course, I looked up the official json-schema.org documentation on how to structure a complex scheme, and even got something to work. I now have three schemas, organized during development in a folder structure as follows:
...ANSWER
Answered 2022-Jan-21 at 23:48Like code organization, there is no one right answer. If you are going to reuse a particular schema in a number of different environments, putting it in a separate file can make sense. But if you're only going to use it in one place, it may be more convenient to put it under a $defs
in the same file. You could even give that schema a nicer name to reference it, via $anchor
.

Please help, I just have no clue what is going wrong, I've tried everything... This is a QA test project, based on java17, maven, testng. Integrеtion between Jenkins and Allure doesn't work, what is going wrong?
I have post condition in Jenkins file :

Answered 2021-Nov-26 at 15:41I found the answer by myself, this is some kind of issue in fresh versions of allure-commandline, try to :
- install old version, for instance 2.8.0
- then you could install any new version
Seems like in old version, while installation, it's creating path(for ubuntu in my case) in correct direction, and then just update with a new one... Or you can insert installation directory manually and initially install a new version
QUESTION
I am using wso2 apim 3.1.0 I want to enable json schema validation for the json payload. I have referred to the belpw document for setting up json shema validation in wso2 apim https://m-saranki.medium.com/unboxing-json-schema-validator-320-2dd944dae6c0 . I am testing the below API for json schema validation
...ANSWER
Answered 2021-Oct-19 at 16:08- Explanation
I believe you are using wso2am-3.1.0 vanilla pack along with a custom sequence file which probably has a mediator using "json-eval($.)" expression. Please confirm. This is a known issue in the wso2am-3.0.0 and wso2am-3.1.0 vanilla packs.
This is becasue when we use json-eval($.) expression in a sequence in the /repository/deployment/server/synapse-configs/default/sequences directory and when it gets deployed, the synapse is setting the GsonJsonProvider [1] to represent the JSON inside the Jayway JsonPath[2].
Since the GsonJsonProvider is getting loaded, even if we remove the particular sequence file which has the json-eval($.) expression in a property mediator, the issue will still persists until we restart the server.
But, if we do not use the json-eval($.) expression at all in a sequence in the /repository/deployment/server/synapse-configs/default/sequences directory, we will not get the above error when we enable the JSON schema validation as the jsonsmartjsonprovider [3] is used to represent the JSON inside the Jayway JsonPath.
Since the JSON object representation is getting different in the error scenario, it throws the IllegalArgumentException in that case.
- Solution
You can approach one of the following solution as suggested below.
- This issue has been fixed in the latest WUM/updated pack. If you have the WSO2 subscription then you can get the latest update.
- You can deploy a new wso2am-3.1.0 vanilla pack and invoke the API calls without the sequence having json-eval($.) expression.
QUESTION
I am receiving JSON payloads and have two things I want to do with them:
- Validate the payload against a schema
- Filter out fields not included in the schema
The fields I want to filter aren't invalid, I just want to remove them from the JSON I'm working with (for my use case these are PII that we don't want to store).
I've found this library that seems to take care of the filtering for us. The issue I've found is that it doesn't handle references - any objects that have a reference to the object definition don't have data populated when we do the filtering.
We're using this library for schema validation. I was hoping we might be able to use this library to expand the references in the schema so that we can still use the same filtering library. This old issue suggests that in a previous version this was possible using a class called ResolvingSchemaWalker
, but that class has been removed in more recent versions and I haven't been able to figure out how to traverse a schema to resolve references in the more recent versions of the library. The RefResolver class seems to do something similar, but it adds a JsonPointer
that references the object definition rather than replacing the reference with the actual JSON object.
If I need to I might edit my schema manually to remove all the references, but I'd like to avoid that if I can. Is what I want to do with replacing references in the schema possible programmatically? Based on that old issue I found in the json-schema-validator library it seems like it should be and the RefResolver
in the current version of the library seems to be doing most of what I'm looking for, but I haven't been able to figure out how to use it to expand those references in the schema.
If someone can point me to a different filtering library that handles references, that could resolve the issue as well. We're not tied to using this filtering library, but it's the best option I've been able to find and seems to do everything we want apart from the issue with references.
...ANSWER
Answered 2021-Sep-28 at 19:18It's possible to remove all external references (references to other schema documents). This is generally referred to a schema bundling. However, it's not always possible to remove all local references (references within the same schema document like to $defs
/definitions
).
Bundling is actually really easy. Here are some references.
- https://json-schema.org/understanding-json-schema/structuring.html#bundling
- https://json-schema.org/blog/posts/bundling-json-schema-compound-documents
Inlining local references ranges from trivial to hard to impossible. If there are no references in the sub-schema being inlined, then a simple replacement can work. If the sub-schema being inlined has references, you might have to rewrite those references because their target might have been moved as well. If the schema is recursive, the fully inlined schema would be infinitely large. Of course you could limit the recursion depth and only have a very large schema instead of an infinitely large schema.
So, if your tooling doesn't handle local references, it's pretty much useless and there's not much you can do. If your tooling just doesn't handle external references, that shouldn't be a problem. It's easy enough to bundle a schema by hand. You don't even need additional tooling.
QUESTION
Hi I am trying to deploy a Spring Boot Application to Heroku. The build is a success but when I try to run the app I get a Status 503: Service Unavailable
Error.
I referred a similar post Application Error after a successful deployment at Heroku but this didn't helped me.
Here is my pom.xml
...ANSWER
Answered 2021-Sep-02 at 19:16I had this same problem! The easiest solution for my case was to just use a Java 1.8 project - Heroku auto defaults to 1.8.
According to the Java Heroku docs here, the supported version are as follows:
- Java 7 -
1.7.0_312
- Java 8 -
1.8.0_302
- Java 11 -
11.0.12
- Java 13 -
13.0.8
- Java 15 -
15.0.4
- Java 16 -
16.0.2
It seems you're using Java 11. To tell Heroku this, make a file called system.properties
in your resources folder. In system.properties
, add java.runtime.version=11
. I believe you can also do java.runtime.version=11.0.12
.
Hope this helps! Review the docs for more information.

Answered 2021-Jul-27 at 18:23The specification states that the default value must match the first element of the union: https://avro.apache.org/docs/current/spec.html#Unions.
Therefore you need to change the order of your union to have the null
type first, or change the default to be an integer type.
QUESTION
New to Scala and Java, coming from Python & JavaScript.
Not looking for solutions involving Spark.
I need suggestions with and without an external library ( like https://github.com/java-json-tools/json-schema-validator, please suggest if there is something better) to validate.
I aim to validate a JSON (available to me in a multiline file of json type) against a provided json-schema (draft-4 version) and print around what value(s) it did not comply.
Here is what I tried, not sure how to proceed further with validating JsonObject (as recieved at parsedJson variable) with the schema I have. For the method where I don't want to depend on an external library to validate, do I write multiple if...else conditions to check the validity of given JSON file? please suggest better approaches, I have no knowledge of Java and Scala.
...ANSWER
Answered 2021-Jun-03 at 15:55java-json-tools/json-schema-validator seems not to have been updated for some time. I'd probably pick one of the libraries listed here. These two seem to be most actively maintained: everit-org/json-schema and networknt/json-schema-validator.
networknt/json-schema-validator
works with Jackson, which is one of the most popular JSON libraries in the Java world, so it should suit your needs. Here's a simple example of how you could validate a JSON object and print errors (I omitted error handling for the sake of simplicity):
QUESTION
I'm new to JSON schema, so bear with me. My goal is to have a JSON property that is an object. It's keys relate to each other, meaning multiple keys always have the same values together. This will probably help make it clear, it's my attempt to do this with an enum:
...ANSWER
Answered 2021-May-20 at 21:38It was news to me, but according to the spec it does seem that objects are valid enum values. That said, your usage is quite unusual. I've not seen it used before.
the six primitive types ("null", "boolean", "object", "array", "number", or "string") ...
6.1.2. enum ...
Elements in the array might be of any type, including null.
Your problem is fundamentally that the library that you're using doesn't know how to convert those objects to printable strings. Even if it did give it a reasonable go, you might end up with
QUESTION
I use networknt:json-schema-validator 1.0.42.
I have been given a (intended) jsonschema with "repuired" (in stead of "required") as a top property key, in stead of a topmost key.
The schema factory (V7) happily ignores this and the validator then, of course, allows instance json not have the keys that were intended required.
I am surprised it can happen unless it is a bug.
I corrected the jsonschema concerning these two problems and added "additionalProperties": false
just after the corrected and replaced line.
May be this part (the line I added) is missing in the metaschema but I suspect it may be for good, but don't know why, as I am new to JSON schema.
I prefer asking before filing a bug.
...ANSWER
Answered 2021-Apr-30 at 13:05The JSON Schema spec (all drafts) says that unknown keywords are to be ignored. The meta-schema not having "additionalProperties": false
is correct.
I can't speak to this implementation specifically, but this is likely what's happening.
