Likely we just need to add this other flavour of "context canceled" to the allowlist in the requireNoFeedsFail helper

[sanki92]

Fixed by adding the grpc connection closing error to the allowlist in requireNoFeedsFail.

The test was failing when it encountered "grpc: the client connection is closing" during connection teardown. This is a normal cancellation error similar to "context canceled" that's already ignored.
