Hi Team, I am working on a new target i.e. target-jira and facing one issue when target is processing the records, Even though my records are in proper format like - first schema and then records, still I am getting issue like -

singer_sdk.exceptions.RecordsWithoutSchemaException: A record for stream 'accounts' was encountered before a corresponding schema. Check that the Tap correctly implements the Singer spec.

Full Error Log:

    raise RecordsWithoutSchemaException(msg)
singer_sdk.exceptions.RecordsWithoutSchemaException: A record for stream 'accounts' was encountered before a corresponding schema. Check that the Tap correctly implements the Singer spec.

I have attached few files for reference.

It might help to look at the code. My guess is that the schema message is not being process and the corresponding sink is not being created

sure. One more observation is - when I am keeping only SCHEMA line (Only the first line of the out_cleaned.jsonl), then its able to proceed. The issue comes when Records come into the picture.
