AccessToken is null

[GabrielMMI]

Hello, I would like some help, I downloaded the git project and made the settings of Read Me, but when I run the program, the "acessToken" token is null, so the Authorization is null as shown in the code below.

 --> POST https://login.microsoftonline.com/9188040d-6c67-4c5b-b112-36a304b66dad/oauth2/v2.0/token http/1.1
Content-Type: application/x-www-form-urlencoded
Content-Length: 230

client_id=0b1ecc07-730f-46e8-a496-fd9c3c7f287e&client_secret=wc%3D9r%40rcaB7-fx.0jKSEufosz4EB--e5&grant_type=authorization_code&code=Mb72647ff-e0dc-0d6c-86ab-1050985d4d80&redirect_uri=http%3A%2F%2Flocalhost%3A8080%2Fauthorize.html
--> END POST (230-byte body)
--> GET https://graph.microsoft.com/v1.0/me http/1.1
User-Agent: java-tutorial
client-request-id: 10165330-8012-4d79-a93b-c488390775b3
return-client-request-id: true
Authorization: Bearer null
--> END GET

It sounds like your authentication is not succeeding. A network trace might shed some light here.

Sorry, I meant a trace showing the traffic to login.microsoftonline.com.

Closing this issue as I'm archiving this sample. We've retired the tutorial that this is based on and we're redirecting to the Microsoft Graph tutorial at https://docs.microsoft.com/graph/tutorials/java. The corresponding GitHub repo is https://github.com/microsoftgraph/msgraph-training-java.
