OPAL is an administration layer for Open Policy Agent (OPA), detecting changes to both policy and policy data in realtime and pushing live updates to your agents. OPAL brings open-policy up to the speed needed by live applications. As your application state changes (whether it's via your APIs, DBs, git, S3 or 3rd-party SaaS services), OPAL will make sure your services are always in sync with the authorization data and policy they need (and only those they need). Check out our main site at OPAL.ac and this video briefly explaining OPAL and how it works with OPA.

QUESTION
Not able to figure out why in upload.js file in the below code snippet is throwing me an error: app.get is not a function.
I have an index.js file where I have configured everything exported my app by module.exports = app and also I have app.set("upload") in it, but when I am trying to import app in upload.js file and using it, it is giving an error error: app.get is not a function.
below is the code of the index.js
...ANSWER
Answered 2022-Mar-23 at 08:55The problem is that you have a circular dependency.
App requires upload, upload requires app.
Try to pass app as a parameter and restructure upload.js to look like:
QUESTION
Edit: Changed title to reflect the problem properly.
I am trying to pick the exact type definition of a specific property inside a interface, but the property is a mapped type [key: string]: . I tried accessing it using T[keyof T] because it is the only property inside that type but it returns never type instead.
is there a way to like Pick or Interface[[key: string]] to extract the type?
The interface I am trying to access is type { AWS } from '@serverless/typescript';
ANSWER
Answered 2022-Feb-27 at 19:04You can use indexed access types here. If you have an object-like type T and a key-like type K which is a valid key type for T, then T[K] is the type of the value at that key. In other words, if you have a value t of type T and a value k of type K, then t[k] has the type T[K].
So the first step here is to get the type of the functions property from the AWS type:
QUESTION
based on the aws documentation, maximum timeout limit is less that 30 seconds in api gateway.so hooking up an sagemaker endpoint with api gateway wouldn't make sense, if the request/response is going to take more than 30 seconds. is there any workaround ? adding a lambda in between api gateway and sagemaker endpoint is going to add more time to process request/response, which i would like to avoid. also, there will be added time for lambda cold starts and sagemaker serverless endpoints are built on top of lambda so that will also add cold start time. is there a way to invoke the serverless sagemaker endpoints , without these overhead?
...ANSWER
Answered 2022-Feb-25 at 08:19You can connect SageMaker endpoints to API Gateway directly, without intermediary Lambdas, using mapping templates https://aws.amazon.com/fr/blogs/machine-learning/creating-a-machine-learning-powered-rest-api-with-amazon-api-gateway-mapping-templates-and-amazon-sagemaker/
You can also invoke endpoints with AWS SDKs (eg CLI, boto3), no need to do it for API GW necessarily.

QUESTION
I have created a RDS cluster with 2 instances using terraform. When I am upgrading the RDS from front-end, it modifies the cluster. But when I do the same using terraform, it destroys the instance.
We tried create_before_destroy, and it gives error.
We tried with ignore_changes=engine but that didn't make any changes.
Is there any way to prevent it?
...ANSWER
Answered 2021-Oct-30 at 13:04Terraform is seeing the engine version change on the instances and is detecting this as an action that forces replacement.
Remove (or ignore changes to) the engine_version input for the aws_rds_cluster_instance resources.
AWS RDS upgrades the engine version for cluster instances itself when you upgrade the engine version of the cluster (this is why you can do an in-place upgrade via the AWS console).
By excluding the engine_version input, Terraform will see no changes made to the aws_rds_cluster_instances and will do nothing.
AWS will handle the engine upgrades for the instances internally.
If you decide to ignore changes, use the ignore_changes argument within a lifecycle block:

QUESTION
We are a team of 5 developers working on a video rendering implementation. This implementation consists out of two parts.
- A live video preview in the browser using angular + konva.
- A node.js (node 14) serverless (AWS lambda container) implementation using konva-node that pipes frames to ffmpeg for rendering a mp4 video in higher quality for later download.
Both ways are working for us. Now we extracted the parts of the animation that are the same for frontend and backend implementation to an internal library. We imported them in BE and FE. That also works nicely for most parts.
We noticed here that konva-node is deprecated since a short time. Documentation says to use canvas + konva instead on node.js. But this just doesn't work. If we don't use konva-node we cannot create a stage without a 'container' value. Also we cannot create a raw image buffer anymore, because stage.toCanvas() actually returns a HTMLCanvas, which does not have this functionality.
- So what does konva-node actually do to konva API?
- Is node.js still supported after deprecation of konva-node?
- How can we get
toBuffer()andnew Stage()functionality without konva-node in node.js?
ANSWER
Answered 2021-Sep-27 at 21:36So what does konva-node actually do to konva API?
It slightly patches Konva code to use canvas nodejs library to use 2d canvas API. So, Konva will not use browser DOM API.
Is node.js still supported after deprecation of konva-node?
Yes. https://github.com/konvajs/konva#4-nodejs-env
How can we get toBuffer() and new Stage() functionality without konva-node in node.js?

Install opal
You can use opal like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
