hey, I'm trying to use this api POST /v1/scheduler/sources/discover_schema to fetch source streams with following body But it raised me the following error Could anyone help me with an example since the documentation is poor for this api

"message": "Invalid json input. Unrecognized field \"sourceId\" (class io.airbyte.api.model.generated.SourceCoreConfig), not marked as ignorable (3 known properties: \"connectionConfiguration\", \"sourceDefinitionId\", \"workspaceId\"])\n at [Source: (org.glassfish.jersey.message.internal.ReaderInterceptorExecutor$UnCloseableInputStream); line: 3, column: 16] (through reference chain: io.airbyte.api.model.generated.SourceCoreConfig[\"sourceId\"]) Unrecognized field \"sourceId\" (class io.airbyte.api.model.generated.SourceCoreConfig), not marked as ignorable",
    "exceptionClassName": "com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException",

(edited) body

{
  "sourceDefinitionId": "36c891d9-4bd9-43ac-bad2-10e12756272c",
  "sourceId": "defac237-4986-45d2-9e92-7d7ecfd3b4ae",
  "connectionConfiguration": {
    "start_date": "2017-01-25T00:00:00Z",
    "credentials": {
      "client_id": "****",
      "client_secret": "****",
      "refresh_token": "*****",
      "credentials_title": "OAuth Credentials"
    }
  },
  "workspaceId": "4f3fe24e-5ca9-48e8-8191-a2638cd30229"
}

after remove the sourceId, get this error

"message": "Internal Server Error: Cannot invoke \"java.util.UUID.toString()\" because the return value of \"io.airbyte.config.SourceConnection.getSourceId()\" is null",    "exceptionClassName": "java.lang.NullPointerException",

Based on the information provided in the extracts, it seems like the error is due to the unrecognized field "sourceId" in the JSON input. The

SourceCoreConfig

class only recognizes the following properties: "connectionConfiguration", "sourceDefinitionId", and "workspaceId". The error message you're seeing after removing the "sourceId" field suggests that the

SourceConnection.getSourceId()

method is returning null, which is causing a NullPointerException when the

toString()

method is invoked on it. Unfortunately, the extracts do not provide a direct example of the correct usage of the

POST /v1/scheduler/sources/discover_schema

endpoint. However, based on the information from the [Slack conversation](https://airbytehq.slack.com/archives/C021JANJ6TY/p1666381521924919), it seems that the "sourceId" field is not required or recognized by the

SourceCoreConfig

class. You might want to check the official Airbyte documentation or reach out to the Airbyte community for more specific guidance on how to correctly use this API endpoint.
