Can't understand/find error in JSON config file referenced by Unity logs

Asked 2021-Apr-05 at 14:19

I have customized this JSON config file for a mod from the game Valheim. The mods make use of a Unity program in order to load the mods up and it shows a console log so you can find errors while loading the game with said mods. I am getting this constant error in the Unity console regarding the file, but cannot understand the error or find any errors in the files JSON formatting.

The error is as follows

ANSWER

Answered 2021-Apr-05 at 14:19

What the error message is saying is that 14451th character is wrong (from the json parser's point of view).

This character index is not very helpful to me. So, to explore this further, I've removed the comments with a regex (in the regex101 link, click on "substitution" on the left panel to see the version without comments). [*]

Then I pasted the comment-less version in an online JSON parser.

The output is a bit more precise:

The desired document would be invalid according to the JSON API specification. You would need to include next and previous links in a link section. The current and total_count would belong in the meta section.

ANSWER

Answered 2020-Dec-31 at 15:28

As far as I know, there is no MyBatis integration in:

neither Spring Data Neo4j 5 (added via spring-boot-starter-data-neo4j in your POM, included up until Spring Boot 2.3)
nor Neo4j OGM (which is the library Spring Data Neo4j 5 is built upon).

If you want to get started, you should probably get started with Spring Data Neo4j 6 (aka SDN 6), i.e. the latest version of Spring Data Neo4j at the time of writing. If you upgrade Spring Boot to the latest version (2.4 at the time of writing), you will automatically get it.

You should probably start with the reference documentation of SDN 6. You also can find an example here.

As you will learn, you can get rid of MyBatis, SDN 6 (and 5 via Neo4j OGM) takes care of the mapping already.

Spring's complaint is that you haven't defined a Bean of type ProjectMapper, which it is saying that it needs to satisfy an Autowire request. Looking at your code, I don't see a definition for such a Bean in what you've shown us here.

The exact point of the problem is hidden, I'm guessing, because you aren't showing us the definition of the ServiceImpl class. My guess is that that's where the actual reference is that Spring is trying to wire up. Apparently, the field name is baseMapper.

Missing org.apache.parquet.hadoop.ColumnChunkPageWriteStore(org.apache.parquet.hadoop.CodecFactory$BytesCompressor,org.apache.parquet.schema.MessageType,org.apache.parquet.bytes.ByteBufferAllocator,int) [java.lang.NoSuchMethodException: org.apache.parquet.hadoop.ColumnChunkPageWriteStore.(org.apache.parquet.hadoop.CodecFactory$BytesCompressor, org.apache.parquet.schema.MessageType, org.apache.parquet.bytes.ByteBufferAllocator, int)]

Means you are using the Constructor of ColumnChunkPageWriteStore, which takes in 4 parameters, of types (org.apache.parquet.hadoop.CodecFactory$BytesCompressor, org.apache.parquet.schema.MessageType, org.apache.parquet.bytes.ByteBufferAllocator, int)

It cant find the constructor you are using. That why NoSuchMethodError

According to https://jar-download.com/artifacts/org.apache.parquet/parquet-hadoop/1.8.1/source-code/org/apache/parquet/hadoop/ColumnChunkPageWriteStore.java , you need 1.8.1 of parquet-hadoop

Change your mvn import to an older version. I looked at 1.8.1 source code and it has the proper constructor you need.

Since you didn't mention it above: did you instrument a Go application? The Elastic APM Go "Agent" is a package which you use to instrument your application source code. It is not an independent process, but runs within your application.

So, first (if you haven't already) instrument your application. See https://www.elastic.co/guide/en/apm/agent/go/current/getting-started.html#instrumenting-source

Here's an example web server using Echo, and the apmechov4 instrumentation module:

Getting NoSuchMethodError (DestinationAccessor) when launching Spring Boot project with generated Java VDM

Asked 2020-Jul-31 at 13:16

I'm building a Spring Boot project making use of S/4HANA custom OData Service and Java VDM. I have been following various tutorials on SAP Blog, developer.sap.com or S4H13 course - the approach is pretty much the same. I managed to successfully generate VDM for my Custom OData Service based on the edmx file, created all necessary commands, methods in the controller and so on.

Unfortunately, I'm encountering an issue when launching the project locally. I use the following command first: mvn clean package and later, when I'm in the application directory want to run the project: mvn spring-boot:run.

The project build fails with the following errors and exceptions:
