flutter User.Read azure active directory "Insufficient privileges to complete the operation&quo-CodePudding

I am trying to get the data of a signed in user using Microsoft graph API. I work with the "aad_oauth" package in flutter. When signing in, an access token is provided. This access token is then used in a http.get request.

However every time I try to get the data, the following error appears. "{"error":{"code":"Authorization_RequestDenied","message":"Insufficient privileges to complete the operation:"

I also added a permission at the ad admin center.

That's how I get the access token

This is my http request

I tried to reproduce the same in my environment and got the below results:

I created an Azure AD application and added user.read permission:

Now I generated access token via Postman with below parameters:

GET https://login.microsoftonline.com/TenantID/oauth2/v2.0/token
grant_type:authorization_code



client_id:1b323717-80d8-4172-b141-XXXXXX
client_secret:GTT8Q~PErY3nTbj9LO8Nkkm2ai.XXXXXXX
scope:user.read
code:code
redirect_uri: redirect_uri

To get the details of the signed-in user, I ran the below query by including bearer token:

GET https://graph.microsoft.com/v1.0/me/
