Running as a root brings new problems, which I did not investigate further:
ubuntu@ubuntu:~$ docker run --rm -it -e PUID=0 -e PGID=0 -v $PWD:/volume1 -v data:/data -p 5454:5454 rednoah/filebot:xpra
+ xpra start --start-child=filebot --exit-with-children --bind-tcp=0.0.0.0:5454 --tcp-auth=none ...

In the meantime, I read a little bit more in the xpra docus and especially the python-uinput does not seem to be important. See https://xpra.org/trac/wiki/FAQ for more information.

It seems that my main problem was an access rights problem. I can successfully start the container with docker run ...

I didn't have time to look into the problem in the last days.
Today, I wanted to, but the situation changes completely.
I assume this is due to your commits
- 0fad2a9a1d0c19c130d7b023cf016075e2c4d414, which creates the folder I mention in my error log.

Hello,

I can't start the filebot-xpra docker container on my Pi 4.

The following console interaction shows what happens and the error messages I receive:
ubuntu@ubuntu:~/repos/filebot-docker$ docker run --rm -it -v $PWD:/volume1 -v data:/data -p 5454:5454 rednoah/filebot:xpra
+ xpra start --start ...

Via some further experimenting, I found a solution.

I only had to do one change in the file node/opt/filebot-node/start :

-exec node --optimize_for_size "/opt/filebot-node/server/app.js"
+exec node "/opt/filebot-node/server/app.js"


However, I did not try to find out why the optimize_for_size ...

First, thank you very much for your response.

I deleted all images using :
docker rmi -f $(docker images -a -q)
Afterwards, I also checked that all images are gone.

Then, I tried:
docker run --rm -it -v $PWD:/volume1 -v data:/data -p 5452:5452 rednoah/filebot:node
The behavior did not change ...

Hello,

I can't start the filebot-node docker and I'm completely lost, as there is not output anywhere.
I use a Pi 4 and run a non-root docker.

I tried the following commands:
docker run --rm -it -v /mnt/exthdd/plexLibrary:/volume1 -v data:/data -p 5452:5452 rednoah/filebot:node
docker run --rm ...
