"Create importedDeviceIdentity" doesn't work

Question

I cannot create importedDeviceIdentity by using the following API.
https://learn.microsoft.com/en-us/graph/api/intune-enrollment-importeddeviceidentity-create?view=graph-rest-beta

Remote Server Error (400) is returned even if I execute the request using the example in the document.

@Sho Narita Thanks for posting in our Q&A.
For our issue, I have done some tests. Through the graph explorer test, the returned result is failed. We have analyzed some code reasons, which are beyond our ability scope. With the limitation of Q&A forum, It is better to create an online support ticket to handle this issue. It is free. Here is the online support link and hope it will be resolved as soon as possible.
