### Tell us what’s happening:

My code raised an error and then this was explained to me running tests

- Your code raised an error before any tests could run. Please fix it and try again.

// tests completed

The only problem is that it doesn’t explain the problem in detail or how to fix it where can I begin to debug my code to fix the issue.

### Your code so far
