Hi, As this issue is with the Confluent Schema Registry, I'm not sure if this message is appropriate here, but I'll ask any way :)
We're trying to query the Confluent Schema Registry, which is a external hosted service we're using, to find all available schemas. The Schema Registry we are using is protected by a basic username/password combination. When we try to use the CachedSchemaRegistryClient (io.confluent.kafka.schemaregistry.client) to query the schema registry, we're passing the full url, eg: https://username:passw...@schemaregistry.url/. Unfortunately this doesn't seem to work, it's throwing the following exception: io.confluent.kafka.schemaregistry.client.rest.exceptions.RestClientException: No content to map due to end-of-input at [Source: sun.net.www.protocol.http.HttpURLConnection$HttpInputStream@4808bc9b; line: 1, column: 1]; error code: 50005 at io.confluent.kafka.schemaregistry.client.rest.RestService.sendHttpRequest(RestService.java:170) at io.confluent.kafka.schemaregistry.client.rest.RestService.httpRequest(RestService.java:188) at io.confluent.kafka.schemaregistry.client.rest.RestService.getAllSubjects(RestService.java:386) at io.confluent.kafka.schemaregistry.client.rest.RestService.getAllSubjects(RestService.java:381) at io.confluent.kafka.schemaregistry.client.CachedSchemaRegistryClient.getAllSubjects(CachedSchemaRegistryClient.java:186) at tv.mycujoo.dataplatform.adapters.source.kafka.SchemaFetcher.fetch(SchemaFetcher.java:30) at tv.mycujoo.dataplatform.adapters.source.kafka.KafkaAdapter.getAvailableSchemas(KafkaAdapter.java:23) at tv.mycujoo.dataplatform.Application.main(Application.java:19) Exception in thread "main" java.lang.NullPointerException at java.util.ArrayList.<init>(ArrayList.java:178) at tv.mycujoo.dataplatform.adapters.source.kafka.SchemaFetcher.fetch(SchemaFetcher.java:35) at tv.mycujoo.dataplatform.adapters.source.kafka.KafkaAdapter.getAvailableSchemas(KafkaAdapter.java:23) at tv.mycujoo.dataplatform.Application.main(Application.java:19) Would anyone know whether this is a known issue and if there's a way around it? Thanks! -patrick
