You may debug these error in Workspaces or locally by running the command:
python app_tests.py
This will help you pinpoint where the errors are hiding. Here are some of the errors seen:
tacocat.py
indent error line 37
indent error line 113
indent error line 120
forms.py
typo line 3
'Email' not defined line 17
Note: if you get the error "Exception: Install 'email_validator' for email validation support.
", as I did since I was running an old workspace environment. I fixed this error using "pip install email_validator
" in the command window.
Post back after you've worked through these is you still need help. Good luck!!
