Hi @FractalMath, thanks so much for reaching out for support. I maintain this training and hope that I can be of service.
I attempted to duplicate your error and was unable to do so. When I visit the training and do make profile from within section 04, everything works as expected.
That said, I believe that if you spin up the content again, you will likely find it working as expected, though please let me know if that is not the case.
I was able to find a bit more information on the error you displayed on this Developer Forum Thread. It looks like there is some kind of timeout occurring with QdstrmImporter which can often be caused by either a massive qstrm file, which I have no reason to believe is true in your case, or perhaps some underlying issue on the VM you were working on. If it were the latter, it is my hope that restarting the training will solve the issue for you.
Again, please do let me know if restarting the content does not solve your issue and I’ll be eager to help get you unblocked. Thanks so much for your interest in the course.
