Start by reproducing the Microsoft.Intune locations and locations/{hostName}/apps requests shown in the issue and compare the returned error with the documented API behavior. Review the relevant Azure REST specification entry, if present; done means identifying the cause and defining a concrete specification or endpoint correction.
