ya,i was also having such annoying error when i started the course.the course should be reviewed i think.the solution is,after only doing the code for the challenge in the replit run it and see if your code passes in the console and if it does stop it,copy the live url link and paste it in the FCC and run the tests.the reason is as you can see in the browser output in the replit when you run the code it loads the initial template provided by FCC but suddenly crushes and keeps saying Replit waking up .
so,doing what i mentioned above does is when you run the test on FCC first by stoping it in replit it prompts the replit to run again and pass the test before the replit crashes again.
Yes, repls crash whenever QA tests run on these projects. As aynuman19 says, you need to do the following for all projects which have QA tests running:
Complete the code for the challenge
STOP your repl (if running)
Enter the live project link on the FCC site (this will wake up your repl automatically)
For later challenges/projects, when you are writing logic/routing code in addition to QA tests (QA Certification), you will have the option prevent the QA tests from running when not required, so you can work on your repl without it crashing.
