Hello,
I’ve been struggling with this for over a week now. I have finished and did RUN THE TEST - PASSED, and the moment I get to the SUBMIT AND GO TO THE NEXT CHALLENGE, my problems start. This button for some reason doesn’t allow me to finish this challenge and complete my certification.
It is a bug.

### Describe the Issue
When completing the RWD portfolio certificate challenge … and clicking "Go to next challenge" (or using Ctrl + Enter) an error is thrown in the browser console and it does not advance to the next challenge. I have _not_ tested this as signed-in or with other certificate challenges.
> Uncaught TypeError: Cannot read properties of null (reading 'includes')
