   My guess is that the bug is in this code you have not revealed and it 
sometimes return None in some circumstances. there is literally no other way to 
see it happening.
   
   I suggest you make an experiment and for example save results of your 
"internal_method" call in files somewhere in tmp directory and print the 
location of those files. That should not cause too much of an overhead and you 
should be able to correlate the return of that function with the failure and 
see where the "null" value comes from. For comparision you can also modify 
Airflow's source code just before ` self._expand_mapped_kwargs(context, 
session)` and also log the values that `expand` method receives. That would 
give even more understanding where it comes from and by narrowing it down to 
the case where you can correlate all of those you can provide more information.
   
   We have no idea to investigate it otherwise, so there is no point in keeping 
that issue open, I am converting it into a discussion and if you have results 
of your experiment, we cam attempt to help again, but without those details 
there is no much help we can give to help to solve your problem - we cannot 
debug your code, I am afraid.
