Here is my current analysis of the Knative workflow failure:
- Some tests that covers SinkBinding fail, as the Knative eventing webhook
fails to inject the `K_SINK` environment variable, which leads to Integrations
being unable to resolve the sink channel:
`java.lang.IllegalArgumentException: Unable to find a resource definition
for channel/sink/messages`
- The Knative eventing webhook fails because it reports the sink channel
referenced in the SinkBinding does not exist:
```json

}
```
- But evidences from the tests and the Knative InMemoryChannel controller
indicate the sink channel actually exists
- Running each of these tests individually succeeds, while running two of
them sequentially produces the error, despite the fact they run in different
namespaces
I haven't been able to reproduce the error locally, so that seems
environment specific, which complicates the production of a simple reproducer.
Someone with deeper knowledge about the Knative eventing internals may help
troubleshooting the issue, and possibly identifying the root cause.
