Error: An error has occured.
When testing the Lightmeter Docker image, an error is thrown:
Error: An error has occurred. Check your logs or contact the app author for clarification.
This happens when running the container with
docker run -v /var/log/:/logs:ro --network weave lightmeter/lightmeter-controlcenter
It first tries to read alternatives.log
and fails, but also doesn't succeed with mail.log
nor mail.log.1
The server starts up with

[2020-01-30T19:12:08.405] [INFO] shiny-server - Created user bookmark state directory: /var/lib/shiny-server/bookmarks/shiny
but ceases to show any other meaningful logs.
What would be the best steps to debug this situation?
