Connector gateway returns 406 for non-JSON `Accept` headers

Observed behavior:

  • Accept: application/json → 200
  • Accept: */* → 200
  • Accept: text/event-stream → 406
  • Accept: application/x-git-* → 406
  • No Accept header → 200
  • Separate Accept headers are not combined

Is this intended? The connector documentation says Custom API connectors support any token-authenticated HTTP API
