Looks like it's back? Or at least something very similar (in this case a
timedelta not being json serializable). Should I create a new ticket for this
or just add my log here?

Ooops!
Something bad has happened.
Airflow is used by many users, and it is very likely that others had similar
problems and you can easily find
a solution to your problem.
Consider following these steps:
* gather the relevant information (detailed logs with errors, reproduction
steps, details of your deployment)
* find similar issues using:
* [GitHub Discussions](https://github.com/apache/airflow/discussions)
* [GitHub Issues](https://github.com/apache/airflow/issues)
* [Stack Overflow](https://stackoverflow.com/questions/tagged/airflow)
* the usual search engine you use on a daily basis
* if you run Airflow on a Managed Service, consider opening an issue using
the service support channels
* if you tried and have difficulty with diagnosing and fixing the problem
yourself, consider creating a [bug
report](https://github.com/apache/airflow/issues/new/choose).
Make sure however, to include all relevant details and results of your
investigation so far.
