I am using a Synology NAS with Docker container - latest version as of this writing, end of Jan 2026.

I followed step by step the latest docker file available available on github, https://github.com/krayin/krayin-docker. I ran setup.sh via ssh.
I made the changes as mentioned in the latest pull request - minor changes, updated version to 2.1.6.

I made sure to copy all the files - although I still get this error:

Looking at stackoverflow, it seems that this error is due to a file not being copied correctly - the Dockerfile might need updating. Not sure - any help would be much appreciated
