Networkerror when attempting to fetch resource (javascript)
I was recently running into this error when doing a JS fetch request. The odd thing was that it wasn’t a CORS issue, which my googling seemed to suggest, as it occurred without an XHR request being fired off.
After pulling my hair out for a while, I finally discovered that uBlock Origin was blocking the request because it had the word “tracking” in it. While the request was tracking nothing, it was being blocked, just because of that verb.
After a rename, everything works as expected!
