Graph API Security Alerts properties blank or GUID

Question

When calling https://graph.microsoft.com/v1.0/security/alerts via python the properties returned do not reflect what is in the documentation. I.e : Category (per docs) = category String Category of the alert (for example, credentialTheft, ransomware, etc.).

I'm getting a GUID for category. Other properties like incidentIds are blank...

      "id": "redacted",
      "azureTenantId": "redacted",
      "azureSubscriptionId": "redacted",
      "riskScore": null,
      "tags": [],

      },

      "networkConnections": [],
      "processes": [],
      "registryKeyStates": [],

Anyone have any thoughts?
