Problem with subjects list while fetching subjects about schema-registry-ui

[Antwnis]

Just tested on a CP 3.1.1 schema-registry and it works on our testing environments

To debug it if you open Chrome Dev tools and check the Network tab you'll see the subjects/ request. Does that respond with the subjects that are already registered in the schema-registry ?

For example - see how the response would look like on our servers

curl -X GET https://schema-registry.demo.landoop.com/subjects/

Hi Rafal, did you have a change to look at it ?!

According to the Confluent API - there is no "subject" in the response. However as you can see in the following API call - the 'subject' is actually part of the response

Hello @Antwnis,
sorry for late response. Shortly speaking: everything is working now:)

I've come to the bottem of problem. Regarding Schema Registry everything is as you have described. Endpoint for schema version returns Schema object:

https://github.com/confluentinc/schema-registry/blob/master/core/src/main/java/io/confluent/kafka/schemaregistry/rest/resources/SubjectVersionsResource.java#L75

and this Schema contains subject field here:

https://github.com/confluentinc/schema-registry/blob/master/client/src/main/java/io/confluent/kafka/schemaregistry/client/rest/entities/Schema.java#L36

as you pointed that out.

Problem occurred because our instance is not original Schema Registry (Kafka backend was not an option) and was updated based on documentation.

Thanks for investiagating my problem, thanks to your answer I've managed to quickly investigate what is going on and we've changed the response to meet the original code:)

Finally, schema-registry-ui is working now, as I stated before it looks great!
Thanks for that software:)

Kind regards,
Rafal Kluszczynski
