List all AD Users using Azure Function

Question

Hello,

I am trying to get the list of all active directory users, but I am stuck.

I am using Logic App to trigger my Azure Function and my Azure Function has Managed Identity setup. So I am able to retrieve a token, but when I pass this token to:

GET https://graph.microsoft.com/v1.0/users
Authorization: Bearer {{token}}

then I'm getting the below error:

{
"error": {
"code": "InvalidAuthenticationToken",
"message": "Access token validation failure. Invalid audience.",
"innerError": {
"date": "2021-03-09T08:41:51",
"request-id": "e55aa5b0-c179-4e3c-ad0f-87b5c874cd58",
"client-request-id": "e55aa5b0-c179-4e3c-ad0f-87b5c874cd58"
}
}
}
