<@U06TM7M40RK> Error registering Avro schema … how can i fix this error

The error “Error registering Avro schema” typically indicates an issue with the schema registry configuration or permissions. Here are some steps to help you resolve this issue:

  1. Check Schema Registry Configuration: Ensure that your schema registry is correctly configured and accessible. Verify the URL and authentication details in your configuration. If you are using Confluent Schema Registry, make sure the URL is correct and that any required authentication is set up properly.

  2. Enable Auto Schema Registration: If your schema registry does not allow automatic schema registration, you may need to enable this feature. According to <Tutorial: Use Schema Registry on Confluent Platform to Implement Schemas for a Client Application | Confluent Documentation documentation>, you can enable auto-registration to allow new schemas to be registered automatically.

  3. Check Permissions: Ensure that the user or service account used by DataHub has the necessary permissions to register schemas in the schema registry. This might involve setting up appropriate access control lists (ACLs) or roles.

  4. Use ErrorHandlingDeserializer: As suggested in a <Slack discussion>, configuring an ErrorHandlingDeserializer can help handle deserialization errors gracefully. This involves setting up your Kafka consumer properties to use ErrorHandlingDeserializer for both key and value deserializers.

  5. Check Network Configuration: Ensure there are no network issues preventing access to the schema registry. This includes checking firewall rules, Docker network settings, or any other network configurations.

  6. Review Logs: Check the logs of the schema registry service for any errors or warnings that might indicate why the connection is being refused or why the schema registration is failing.

If you need more detailed steps on any of these points, please let me know.
