The production Early Access version for the new "Developing Advanced Automation with Red Hat Ansible Automation Platform" course (DO374), currently in development, is improperly auto-updating to a version of lab command automation newer than is supported by the "production" Early Access classroom environment. Until this is resolved, as a workaround you can run the following command after starting the classroom environment or rebooting systems, and before running the lab command:
lab install -u --env test --version 0.0.1.dev0+pr555 do374
A banner message will be added to the ROLE web interface for DO374 later today in order to notify the general audience. When that banner message comes back down after a future classroom update, that command will no longer be appropriate.
