SettingWithCopyWarning in job manager

[soxofaan]

reported by Joris C:

Not sure whether it's due to a change in the job manager, or whether it was there already, but I'm getting a warning on the line here:
https://github.com/Open-EO/openeo-python-client/blob/master/openeo/extra/job_management.py#L650
SettingWithCopyWarning:
A value is trying to be set on a copy of a slice from a DataFrame.
Try using .loc[row_indexer,col_indexer] = value instead
See the caveats in the documentation: https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#returning-a-view-versus-a-copy
active.loc[i, "running_start_time"] = rfc3339.utcnow()

I already looked into this issue, but I could not yet reproduce this warning from using the job manager.

I can reproduce it with some simple pandas usage like

df = pandas.DataFrame({"foo": range(10)})
active = df[df.foo % 3 == 0]
active.loc[3, "foo"] = 666

but I would need a more practical usage example of the job manager that triggers this
