Can't find user by email using GraphAPI

Question

I'm using GraphAPI getting users by email for months. Something happened to a specific user. Right now I can't get this user using the following approach:

signInNames/any(x:x/value eq '{email}'

This is working with all users excepting the one I said before.

I'm getting this when trying to retrieve by email:

{ 
  "odata.metadata": "https://graph.windows.net/jsmaddev.onmicrosoft.com/$metadata#directoryObjects", 
  "value":[]
}

If I try to get by ObjectId I can access user's info but the signInNames seems to be empty:

"signInNames":[]

Is there something that could cause this? You should remember that this particular access was working as intended.

Thanks!

Answer 1

This is normal. The filter signInNames/any(x:x/value eq '{email}' returns the users whose signInNames.value equals the email.

The signInNames part sample:

 "signInNames": [
    {
      "type": "userName",
      "value": "AlexW"
    },
    {
      "type": "emailAddress",
      "value": "AlexW@example.com"
    }
  ]

If I try to get by ObjectId I can access user's info but the signInNames seems to be empty

Since the signInNames property is empty, "signInNames":[], it will returns the "value":[].

You should remember that this particular access was working as intended.

Of course, if the signInNames is not empty, it will work fine.
