[SOLVED] Bad Request 400 when making API call to Microsoft Graph

Bad Request 400 when making API call to Microsoft Graph

The error I'm getting from Microsoft Graph API is this

error = {
  "code": "BadRequest",
  "innerError": {
    "date": "2017-04-10T19:37:08",
    "request-id": "973641dd-b150-4406-9f3b-fbcf6f7e5aa1"
  },
  "message": "The MIME type 'text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2' requires a '/' character between type and subtype, such as 'text/plain'."
}

I'm able to successfully get from the endpoint https://graph.microsoft.com/v1.0/me/contacts while using POSTman however going the the scribe-java library OAuthRequest I receive this error.
My request is going to the url https://graph.microsoft.com/v1.0/me/contacts with 2 headers. Authorization -> Bearer [Token]
Content-Type -> application/json

Solution

It turns out the scribe-java library doesn't setup the request correctly. Switching to apache HttpClient and HttpGet resolved the issue for me.
