Error fetching timeline: JSON.parse: unexpected character at line 1 column 1 of the json data

[lightnin]

When scrolling downward on my Pleroma instance, I periodically see the error: Error fetching timeline: unexpected character at line 1 column 1 of the json data - see screenshot.

Instance is here and public if you want to try yourself. https://masto.amosamos.net/lightnin

Apologies if this should be filed upstream - it doesn't seem to be an issue already described there, so I'm not quite sure where the problem lies. This issue started subsequent to upgrade of my yunohost pleroma app from Version 2.4.1~ynh1 to 2.4.2~ynh1.

Context

YunoHost 4.3.6.2 (stable) Pleroma 2.4.2~ynh1 Rpi4

Steps to reproduce

Scroll downward quickly on timeline.

Expected behavior

It scrolls, no errrors.

Logs

Not sure where to find what's needed.

https://git.pleroma.social/pleroma/pleroma/-/issues/2829#note_89365 It looks like it's related to Nginx 502ing. Watching htop while the error happens, it doesn't seem to be putting the server under undue load. Based on comment above, it appears that this is possibly related to Nginx config on Yunohost installs of pleroma.

After multiple reinstalls for some reason this went away Quite annoying.
