richardcann opened a new issue, #27554:
URL: https://github.com/apache/beam/issues/27554
### What happened?
Using Beam versions 2.37.0 and 2.43.0, we are reading from streaming source
Pub/Sub and using a FixedWindow of 30 minutes to aggregate elements and then
group by a key we assigned based on the message. The pipeline works fine for
about ~1hr (I can see windows are getting outputed correctly and process
afterwards) and then it throws the following error around the
IntervalWindowBase:
```

TypeError: Expected tuple, got dict
```
This error also happens when I reduce the size of the window. We are using
Dataflow as the Runner. Input type to the windowing is `Tuple[str, Dict[str,
str]]`
