The problem is that it can be a bit difficult to edit your app to remove the code that’s causing the problem, because it just freezes instantly every time you try to refresh the page and try editing it again. I ended up fixing it after a couple of tries by quickly trying to throw some random characters into my script to cause a restart+syntax error. Might be worth adding some sort of mechanism to rate-limit the errors/logs in the console.
Cheers,
