ashb opened a new pull request, #58959:
URL: https://github.com/apache/airflow/pull/58959
For instance, if you set this config
```ini
[logging]
log_format={%%(filename)s:%%(lineno)d} --- %%(message)s
```
this would blow up with an error like this on printing anything from a
trigger, killing the triggerer process:
```
