I have also been researching on how to get this done with the try/except block. For example if we catch the error but do not raise it, just printing the error to the stdout would cause the current cell to succeeed and continue execution of the next cell and/or task in the flow.

However this is very basic and does not account for specific erros, it is just printing the error you got thus making your code in the notebook cell not to fail, but also exposing you a lot and is not considered best practise at all.

try:
   do_something()
except Exception as e:
   print(e)

Perhaps there is a smarter way to do so if you please give an example of how you achieve the onCompletion status by using the try/except block it in code would be very beneficial.

Thank you.
