Config export fails with PHP fatal error (SQLite permission issue)

Exporting the configuration via Config Import/Export fails with a PHP fatal error when using the Docker image lampro.azurecr.io/lampro:9.3.
The error is caused by insufficient permissions to access the __lam.requestAccess.sqlite file.

Do you mount the conf-directory from outside the container? Maybe the directory is not writable for the Apache user inside the container?
