This is my code. I want the code to stop and to return an error message.
But I get a long error that says assertion error and more. (30+ rows). It should just system Exit: 'Mistake'
Here is the error that I get when running this exact piece of code:
I will copy / this same sentence a few more times, as stackoverflow doesn't let me paste such large error code vs normal text. I will copy / this same sentence a few more times, as stackoverflow doesn't let me paste such large error code vs normal text.
