Calibre-web DB Location is not Valid

Hi there :wave:

I’m trying to spin up a calibre-web instance on my CasaOS install, but I haven’t been able to get past setting up the DB directory. No matter what dir I choose, I get the error message “DB Location is not Valid, Please Enter Correct Path”

Is this a file permissions thing? I have read elsewhere that the .db file itself needs to alre exist, but that doesn’t seem to be the case.

I’m kind of new to self hosting, and am running a raspberry Pi 5 on Debian.

I don’t know if I’m missing important information but I will provide it if needed.
