Docker Run error

[NugentS]

In an attempt to make a backup of my container configuration files I have been running
docker run --rm -v /var/run/docker.sock:/var/run/docker.sock ghcr.io/red5d/docker-autocompose -v 1 $(docker ps -aq) >> mydocker.yml
as a cron job. The file it produced was somewhat useful in working out what I had done with a container, so if I need to set up that container again I at least have a clue and a reminder. I am not expecting the file to be directly useable. This is mostly theory

In 22.02.2.1 this worked just fine - I never tested the result (hope I never have to) but the theory is at least somehat good.
In 22.02.3 I get the output below and unsuprisingly a blank output file

I am not a docker expert so am not sure where to go from here
