Polber opened a new pull request, #33443:
URL: https://github.com/apache/beam/pull/33443
There was a bug with pipeline-level windowing with transforms that define
`error_handling` in which pipelines would fail with error:
```
Ambiguous output at line 16: Stream has outputs [None, 'errors']
```
This was due to a check to ensure a transform only outputs a "good"
collection and optionally a collection defined by the named output in the
`error_handling` config. Since the `error_handling` was not propagated to the
top-level composite constructed as part of pipeline-level windowing, the check
would fail.
Example affected pipeline:
```
pipeline:
transforms:
- type: ReadFromPubSub
name: Stream
config:
topic: projects/pubsub-public-data/topics/taxirides-realtime
format: json
schema:
type: object
properties:
ride_id: {type: string}
error_handling:
output: errors
- type: LogForTesting
name: Log messages
input: Stream
- type: LogForTesting
name: Log errors
config:
level: INFO
input: Stream.errors
windowing:
type: fixed
size: 60
options:
streaming: true
```
