Missing or invalid config after init

[dabziuebu4egh2]

Hello,

thank you for this project.
I'm trying to set it up with Radicale and I don't need anything else. Init works fine with my provided password but at the next start I receive the following screen:

Here are my logs from my browser console:

Content-Security-Policy: The page’s settings blocked the loading of a resource (media-src) at data: because it violates the following directive: “media-src 'self'” [redacted]

I'm using the external-proxy configuration and it's working from my domain.

.env

COMPOSE_FILE=docker-compose.yml:external-proxy/opencloud.yml:radicale/radicale.yml
START_ADDITIONAL_SERVICES="notifcations,radicale"

docker logs

Thanks for your help.
