Container-agent error on job execution

Build Environment
1

Environment #1
Environment: Azure AKS (v1.21.2)
Helm chart: circleci/container-agent
Helm version: 1.0.10775

Environment #2
Environment: Docker Desktop (v1.21.3)
Helm chart: circleci/container-agent
Helm version: 1.0.10775

When jobs run we get the following error (occurs in both environments):

20:47:45 347f5 55801.845ms service-work error=1 error occurred:
* could not start task containers: exec into build container “primary” failed: error executing command /bin/bash -c echo ‘Starting circleci-agent’; mkdir -p /home/circleci/ccita : Internal error occurred: error executing command in container: failed to exec in container: failed to start exec “9790”: OCI runtime exec failed: exec failed: container_linux.go:380: starting container process caused: exec: “/bin/bash”: stat /bin/bash: no such file or directory: unknown

mode=agent result=error service.name=container-agent service_name=container-agent

The container-agent-* pod seems healthy and shows up in the CCI UI under self-hosted runners with the expected version. When jobs execute I can see the ephemeral ccita-* pod get scheduled. This pod doesn’t seem to have any log output. When following the logs in the container-agent-* I get the above error (also seen in the CCI job UI).

Thanks for the help.
