I've been trying to host my own lemmy instance for a while. i've almost got it working (i think). But my problem now is that whenever i try to post something with a picture i get an error SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data.
In firefox i get a 502 bad gateway error pointing to https://lemmy.emphisia.nl/pictrs/image
I don't really know why because everything seems to be working
yeah I've already done that, I did sudo chown -r 991:991 volumes/pictrs.
what details do you need about my setup?
edit: I do know another program is already using port 8080 on my host machine, or does that not matter when it's running inside docker?
Depends. If it runs in a separated docker network then not. Pict-rs only needs to be reachable by the lemmy backend and have out-going internet access. But I would try changing the port as I think the official docker-compose script removed the internal network for some reason, not sure (I am using my own Podman based setup).
