Actually I just found that the CI runs get the

Error: no such file or directory

error when run again because the location of the Machine Id identity file (an argument in the credential exec command) moves to a new temp location on each run.

I know some will say what is the problem if it works? Well... other users who may not be as deep in the weeds as I am will run into an issue and will report it as the issue when it is really a red herring that obscures the real issue.
