As you can see in the first picture, I also uploaded the URL with the files. Although this is the final project, every single project with CodeAlly has been broken here. Sometimes it takes multiple reports to finally get this addressed and fixed. This should really be taken down until everything is stable. Also, the final task asks you to make sure everything is done in main, yet the project defaults to master.
Nothing worked for a few days until I reported this. Logging did not help. I had to report this on Reddit and discord to get attention after a day. Then, a few days later after “maintenance”, it worked.
