Edit: Don’t know if this correlates, but i tried to export the query results to CSV via the web UI. Even that won’t work. I get the exact same error messages in the graylog-server.log, as when i’m submitting the API call:
2018-02-11 15:10:13,172 ERROR: org.glassfish.jersey.message.internal.WriterInterceptorExecutor - MessageBodyWriter not found for media type=text/csv, type=class org.graylog2.rest.resources.search.responses.AutoValue_SearchError, genericType=class org.graylog2.rest.resources.search.responses.AutoValue_SearchError.
2018-02-11 15:10:13,173 ERROR: org.glassfish.jersey.server.ServerRuntime$Responder - Error occurred when processing a response created from an already mapped exception.
Any other ideas?
