40408 error on /config/subject instead of 40401 cause AKHQ to break

[twobeeb]

When running AKHQ against recent version of Schema Registry, the schema registry is throwing different errors codes than previous versions when calling /config/subject (which is allowed to return 404).

Because the error is not ignored, the SchemaRegistry page completely fails on AKHQ :

This is the failing part, which requires specifically 40401 :
https://github.com/tchiotludo/akhq/blob/dev/src/main/java/org/akhq/repositories/SchemaRegistryRepository.java#L222-L235

Change on Confluent side :
confluentinc/schema-registry#1920

I suggest replacing the above code with :

public Schema.Config getConfig(String clusterId, String subject) throws IOException, RestClientException {
        try {
            return new Schema.Config(this.kafkaModule
                .getRegistryRestClient(clusterId)
                .getConfig(subject)
            );
        } catch (RestClientException exception) {
            // before
            // if (exception.getErrorCode() != ERROR_NOT_FOUND) {
            if (exception.getStatus() != 404) {
                throw exception;
            }

            return this.getDefaultConfig(clusterId);
        }
    }

What's your opinion ?

After upgrading Schema Registry we also observe this problem.
Any chance we could see a release with this fix?

Will do, seems to have a lot of people waiting for a new release 😄
