Error Request failed with status code 500 Internal Server Error

[Shardonnay]

Hello, beforehand I want to thank you for this amazing project !
I'm not sure if this error is really a bug or just a simple permission error.

The problem:
When uploading an attachment or setting a wallpaper I get the following error message: " Error Request failed with status code 500 Internal Server Error". In the docker container log I got the following error message: "ERROR ▶ handler/UploadBackground 1f7 open files/3: permission denied"

My docker compose file looks like the following:
version: '3'

Hi!

That looks a lot like a permission issue.

Vikunja runs as the user 1000:1000 in the container so that user needs to have access to the mounted files folder. Check out this forum thread about the problem: https://community.vikunja.io/t/permission-error-uploading-attachment/425

Thanks @kolaente ! I will now close the issue.
