" sent an invalid response" problem HTML5

Im coding and i see that it says “sent an invalid response” when I tap the run button. I don’t know if I’m doing something wrong but if I do “open website” like to go into a new tab, its not running. This didn’t happen to me before an hour ago. The replit I’m trying to do is an emulator IT might be that or something elese


i have this problem since yesterday. Could somebody help me? I already posted one but no one seemed to care or respond.

Seems that there was a temporary issue that’s now fixed. Now it gives a blank screen due to a syntax error: use " instead of ' around the string on line 8, so that the string doesn’t end at Majora.
