pictrs - IO error: Permission denied (os error 13)

Hello,

I'm new to setting up a lemmy instance. Followed the guide using docker compose. I have everything running for the most part, but I'm noticing this error in the logs.

lemmy-pictrs    | 2024-10-28T01:58:48.048727Z  WARN pict_rs::tmp_file: TmpFolder - Blocking remove of directory "/tmp/pict-rs/0192d0d8-e3ec-7dcd-be4e-d1ef1cc09fca/0192d0d8-e3ed-71d6-a5dc-5dc150e868f1"

Any help on how to go about debugging this would be helpful! As I understand the pictrs container isn't able to access the volume for postgres. But not sure why.
