Do not call logger on None object.

[pdelboca]

This line of code is calling a method right after validating that the object is None.

It causes the following error:

  File "/home/pdelboca/Repos/dathere/datapusher-plus/ckanext/datapusher_plus/jobs/pipeline.py", line 292, in execute
    context.logger.info(f"Pipeline stopped after stage: {stage.name}")
AttributeError: 'NoneType' object has no attribute 'logger'

The above exception was the direct cause of the following exception:
