self hosted lemmy 502 pictrs - eviltoast

Hi,

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

    Hmm not sure. The api-key ENV variable changed with pict-rs 0.4 to PICTRS__SERVER__API_KEY, maybe double-check that this is correctly updated and also the same as in your lemmy.hjson config file.

      PICTRS__SERVER__API_KEY

      the config in docker compose looks like

        pictrs:
    image: asonix/pictrs:0.4.0
    # this needs to match the pictrs url in lemmy.hjson
    hostname: 127.0.0.1
    # we can set options to pictrs like this, here we set max. image size and forced format for conversion
    # entrypoint: /sbin/tini -- /usr/local/bin/pict-rs -p /mnt -m 4 --image-format webp
    environment:
      - PICTRS_OPENTELEMETRY_URL=http://otel:4137
      - PICTRS__SERVER__API_KEY=****
      - RUST_LOG=debug
      - RUST_BACKTRACE=full
      - PICTRS__MEDIA__VIDEO_CODEC=vp9
      - PICTRS__MEDIA__GIF__MAX_WIDTH=256
      - PICTRS__MEDIA__GIF__MAX_HEIGHT=256
      - PICTRS__MEDIA__GIF__MAX_AREA=65536
      - PICTRS__MEDIA__GIF__MAX_FRAME_COUNT=400
    user: 991:991

      and in the config it is

        pictrs: {
    url: "http://127.0.0.1:8080/"
    api_key: "****"
  }

      the password on both is the same so i don’t see what is going wrong :(

          hmm after looking i dont even see an option to change the port (in pictrs). it seems stuck at 8080, but since its running on its own network, i doubt it would matter.

        I haven’t done this setup myself, but the hostname being 127.0.0.1 is suspect, especially since it mentions a pictrs URL config in lemmy.

          yeah i changed that because i was testing. but i now realize that was dumb. ive change both the hostname and the url to pictrs. OMG that just worked… i feel so dumb rn. it is strange tho because that wasnt working before. Thanks for all the help :)
