FrankYang0529 opened a new pull request, #71086:
URL: https://github.com/apache/airflow/pull/71086
### Why
- `DataflowJobMessagesSensor`, `DataflowJobAutoScalingEventsSensor` and
`DataflowJobMetricsSensor` return their payload to XCom when deferred, but drop
it in poke mode. `deferrable` defaults to `False`, so the default path is the
broken one.
- The payload travels through a chain, and these sensors break it at the
last step:
```
poke() → PokeReturnValue(is_done=True,
xcom_value=X)
BaseSensorOperator.execute() → picks X out and returns it
subclass execute() → must return it upwards ← dropped
here
task runner → pushes it as the return_value XCom
```
### How
- Return `super().execute(context)` from the three sensors' `execute()`
overrides. All three were already annotated `-> Any`.
- Wrap `DataflowJobMetricsSensor.poke()`'s result in `PokeReturnValue`, the
same way #53115 did for the other two.
