I have posted anything for a long time.
I have been spending way too much time on this stupid error while developing and testing ServiceWorker as part of a PWA (Progressive Web App), and I hope it can help others who will encounter this problem.
Uncaught (in promise) DOMException: Quota exceeded
The ServiceWorker would not install properly. It turns out I was running low on disk space on my machine (about 200MB left). Deleting some stuff on my hard drive instantly fixed the issue.
Another thing that puzzled me while trying to find the problem was the status shown by the ServiceWorker (in the “Application” tab of the Developer Console, “Service Workers” section). For example (sorry, no screenshot):
Status: #137 is redundant
So there you have it, in case you run in the same problem. I hope this helps.
