Microsoft Graph API 500 Internal Server Error: "Object reference not set to an instance of an object"

Question

Microsoft Graph API 500 Internal Server Error: "Object reference not set to an instance of an object"

I'm currently using the Microsoft Graph API v1.0 and it has been working fine until this morning where we started receiving 500 internal server errors. I cannot figure out what the source of the issue is. Has anyone ever ran into this error? Or can someone point me in the right direction of how to resolve this?

Using this GET endpoint https://graph.microsoft.com/v1.0/me/ returns 500 Internal Server Error response. Currently the only header I'm using is 'Authorization = Bearer {{accessToken}}'

It looks like their graph API is down.
