How do you throw an error from a Notebook so a Data Factory pipeline knows to stop running?

Greetings, all. I am wanting a notebook to throw an error if a condition isn't met, and I want that error to show in a Data Factory pipeline that is triggering the notebook. How can I do this?

    Thanks for the reply, frithjof_v. The challenge there is I'd then need to add logic in the pipeline to evaluate whether or not the exit value output indicates an error.

     

    The solution I found (which I found somewhere on the internet that I don't recall) is to use raise Exception("Error message here"). Here's a modified version of the code block; the vars are just fake examples of operations I am performing:

     

     

    if var == None:
      raise Exception("No match found.")
    else: 
        var2 = var

     

     

    This sends the exception back as an error to the pipeline so the Notebook activity actually fails, which is handy.
