Start with the Azure DevOps build linked in the issue and inspect log entries 16 and 45. Review the 1ES PT image-refresh instructions for the 47-day-old build.azurelinux.3.amd64 image and determine why Bash exited with code 42; done means the synchronization pipeline completes successfully without these errors.
