Unable to submit resources because docker doesn't return logs

Hi, We have an issue running the cfn-cli in our CI/CD system (based on Jenkins) to build and deploy a new version of our resources. The issue is happening while updating an existing resource. Still, I don't think this makes any difference because the issue is related to the logs of the first container used to install the dependencies to build the resource.

Below, I'm attaching all the information I have to help debug the issue in different files.

Instance setup: instance-setup.txt

The command we run:

/usr/local/bin/cfn submit --region us-west-2 -v -v -v --set-default --use-docker

The error:

Build running. Output:
Unhandled exception

I tried to understand what was happening, and I saw that the submit command started and the first container to install the dependencies ran successfully. I collected the following logs from that container:

The container exists with code 0, but the pipeline doesn't show the container logs because it fails running at line being the variable logs equal to None. Because of that, the whole procedure fails with the output above.

Right before the docker daemon removed the container, I was able to inspect the container two times (the first time while it was running, the second one when the container stopped)

Container running: container-running.txt

Container removing: container-removing.txt

The resource definition: resource.json

Thank you for the help
