Week 3 - Trigger Word Detection

Hey @roccoluca,
Welcome to the community. If your implementations are passing all the test cases, and still you are getting this error, then you may try to fetch a new copy of the assignment, and move your code into that, since it seems like you have changed something involuntarily that you were not expected to, or perhaps, this could be a glitch from the Coursera’s side as well.

You can get a clean copy of your assignment by following the instructions in this thread. But make sure to download your existing notebook, so that you can easily copy + paste your code in the new copy. You can find the instructions to download your existing notebook here. Let us know if this helps.
