For anyone still having issues with this section - I had skipped ahead and completed the next 2 challenges, but was stuck on Registration. I just solved it. My code that’s up on Glitch needs to stay current, but I pushed the Registration-specific code here:
To get the first test to pass, I had to backtrack and put everything back into server.js, rather than splitting it up into a few files. There were also a few other small fixes and hacks that were not picked up by the later tests. I think my code is more concise than some of what’s been posted here in the past. Hope this is helpful!
