When I am trying to post a comment, often times I will get this JSON error “unexpected token <”. I wonder if the call is erroring out on the server side and you’re getting an HTML error page back?

Odd thing is that 9 times out of 10, when this happens, the comment will still post. Until i discovered this, I was repeatedly hitting “submit” (since after the error you get sent right back to the comment edit dialog) and repeatedly posting! Now I can identify Memmy users by their repeat comments 😅

Is this a known issue?

I’m on lemmy.world and so it might happen more frequently for me as their servers have been going through some stuff lately…

    If the comment posted, it likely didn’t fail on the backend. It likely is an error parsing the response json.

      The error probably showed up by trying to parse the response of a failed http request

      Well that’s my point - the response isn’t JSON, it’s HTML. “<“ would always be the first character of an HTML document. Probably the 502 errors that have been plaguing the larger instances.
