Test for missing data entry

In my website photos plug-in, if I test for missing data input, how do I get it to print only my gimp message and exit.

I have been searching for this all day and tried numerous things without success.
Most of the things I have tried add additional error messages.

If you exit properly there shouldn't be any. My plugins are usually architected like this:

Code:

import traceback

def pluginImplementation(image,etc...):

    image.undo_group_start() # so that whatever happens, only one single Ctrl-Z to revert
    gimp.context_push() # if the code alters the context, otherwise omitted
    
    try: # start Try/except block
    
        # implementation code goes here. Can call functions
        
        if some_error_case:
            raise Exception('This message will be displayed to the user')
        
        # some more implmentation code
        
    except Exception as e: # catch any exception raised by the code
        pdb.gimp_message(e.args[0]) # Error message to the user
        print traceback.format_exc() # Traceback to terminal for developper
        
    gimp.context_pop() # if there was a push() at the top
    image.undo_group_end() # close the undo group (done whatever happened before, error or success)
