Detail of model returns "internal_server_error" with java.lang.NullPointerException

[zajacjakub]

Versions Please fill in all that apply:

• Convergence Version: 1.0.0-rc.12
• OS: Alpine Linux v3.14
• Browser: Chrome, Postman

Describe the Bug Can't get the detail of the model. It works after the first time the Convergence docker is built and launched, but after some time it starts to return NullPointerException.

The bug first shows in our web app console trying to connect: ERROR Error: An unknown error has occurred, check the server logs for more details.

The admin interface can't get the models of the domain also:

POST http://localhost:3000/api/rest/domains/convergence/dev/model-query
PAYLOAD: {"query":"SELECT\n                   FROM canvases LIMIT 25\n                   OFFSET 0"}
RESPONSE: {"body":{"error_code":"internal_server_error"},"ok":false}

Using REST API in Postman, I can easily get collection of models inside domain: GET http://localhost:3000/api/rest/domains/convergence/dev/models RESPONSE:

{
    "body": [
        {
            "id": "394b8a58-937e-4363-b120-0880041d81c8",
            "collection": "canvases",
            "version": 3935,
            "createdTime": 1664460201437,
            "modifiedTime": 1664478359101
        }
    ],
    "ok": true
}

But Cant get the detail: GET http://localhost:3000/api/rest/domains/convergence/dev/models/394b8a58-937e-4363-b120-0880041d81c8 RESPONSE:

{
    "body": {
        "error_code": "internal_server_error"
    },
    "ok": false
}

Step To Reproduce I apologize for the poor reproduction description. I am still trying to figure out what exactly causes this bug.

1.) Run docker and create container based on image convergencelabs/convergence-omnibus. 2.) Use it freely and without bugs. 3.) Some next time you will run the docker image, the errors starts to show.

Expected Behavior Not resulting in Server error and returning the detail of model.
