Review Comment:
   You’re right — since raise ... from e automatically preserves the original 
exception in __cause__ and Python will include it in the traceback, explicitly 
logging or storing the original exception again isn’t necessary.
   
   Thanks for pointing that out — I’ll go ahead and simplify the code 
accordingly.
