Could not open file version.json: No such file or directory

Hello Geoff and everyone,

I'm trying to host FTB Minecraft server in docker on my QNAP NAS, but getting the error (below) at the very beginning:

I'm quite new with Docker stuff, but with vanilla Minecraft server it works without issues.
If type is set to FTBA with two additional FTB properties for modpack version - it doesn't work...

Here are the settings I've used:

Using GUI to create a container, due to some issues with Docker Compose and NAS I have.

Any ideas what is wrong?

P.S.: eula.txt file is the only one created at the location.

It seems like it has gotten out of sync with what is downloaded. Since there's not yet a "force reinstall" option can you use ls -a to look for the dot/hidden files in your host path? Specifically there's .ftb-installed that if removed will force a reinstall.

Yes, you are right, there was a hidden .ftb-installed. Deleting it fixed the issue and server successfully installed. Thanks a lot Geoff! :)
