Submission 9768399 (Task 2 Validation queue 9619642) returned INVALID. The downloaded workflow logs (`syn75889935`) show every CWL job failing at the same point, before any participant content is read: ``` Error response from daemon: client version 1.41 is too old. Minimum supported API version is 1.44, please upgrade your client to a newer version ... subprocess.CalledProcessError: Command '['docker', 'images', '--no-trunc', '--all']' returned non-zero exit status 1. cwltool.errors.WorkflowException: Docker is not available for this tool, try --no-container to disable Docker, or install a user space Docker replacement like uDocker with --user-space-docker-cmd. ``` Failing tools include `get_submission.cwl`, `synapse-get-tool.cwl#synapse-get`, and `set_permissions.cwl` — all choke on the same `docker images` call. The orchestrator host's Docker daemon is too new for the cwltool/toil v4.1.0 client in the workflow image (API 1.41 vs required 1.44). This is a queue-wide infra issue (independent of any participant content). Could the organisers update the workflow runner image (cwltool/toil) to one supporting Docker API >= 1.44, or pin the host Docker daemon to a compatible version? Happy to provide more logs if useful. Thanks!

Hi all, all tasks are failing, is there a way to tell the organizers to resolve the issue. Thanks!
@adagio correct. Can confirm for task-1a. (submission ID 9768439)
Hello, I think the same issue is happening to all tasks now.
Same issue with Task 1b submission. (submission ID 9768425)
