Bug fixes

  • Fixed a bug that prevented the creation of data models when the app name and app ID are different.

  • Addressed reported CVEs in libraries used by various Fusion services.

  • Fixed a bug that prevented the RPC service from working if the service was run from behind a proxy.

  • Fixed a bug with the Machine Learning stage that resulted in authentication failing when using gRPC authentication headers. The ML library now passes JWT authentication when used as part of a Pulsar subscription as expected.
