Non fatal Job Exception Occurred, the server terminated an operation because it encountered a client request loop
原因
The service account is not using the correct format
対策
In this case if the account is not on the correct format the system will throw that error.
If the service account "TestO365@lab.onmicrosoft.com" the error occur if you have a lowercase " t and o", where office 365/azure expect uppercase "T and O" in the username.
