Unable to access confluent compatible schema from apicurio ccompat v6

Apicurio version: 2.2.3.Final Running on Docker environment using: apicurio/apicurio-registry-sql:2.2.3.Final

curl -X GET -H "Accept:application/json" http://hostname/apis/ccompat/v6/subjects/<subject-name>/versions/latest

This gives 400 with response {"message":"Failed to discover artifact type from content.","error_code":0} and in the logs I can see [Fatal Error] :1:1: Content is not allowed in prolog.

This is happening only for a few schemas.

The same schema can be accessed using the below API for all my schemas.

curl -X GET -H "Accept:application/json" http://hostname/apis/ccompat/v6/schemas/ids/19

I have found the issue. When the type is being discovered getting the schema, the references were not passed down and it was failing because of that. I have created a PR that solves this problem.

There are no updates since it’s pretty difficult to reproduce the issue without the problematic schema. Nothing should be done to map a schema to a subject (if the subject does not exist, it will be created when the schema is created). If you provide more details (schema being used, schema type etc), I can try to reproduce the issue.
