NPE in ServerTransportListenerImpl while running integration test #428

Closed AnkurAnand11 closed 1 year ago

AnkurAnand11 commented 1 year ago

Describe the bug When running the standalone it throws an NPE repeatedly when attempting to startup and shutdown. This prevents some tests from working. In particular all Integration tests for the Rust client fail due to this issue.
