Create assignment with `educationAssignmentPointsGradeType` now return error 400

Question

We have been using the Education Beta Graph API to create an edit assignments for months without issue.
However something has happened in the last day or so to stop this working. No code changes have happened on our side.

Using this endpoint: https://learn.microsoft.com/en-us/graph/api/educationclass-post-assignments
now returns a 400 bad request with the following error message:

Invalid OData type specified: "microsoft.education.assignments.api.educationAssignmentPointsGradeType"

This is an urgent problem as our software is now broken for all customers who utilise the link to their Teams for education.
Please advise of any new OData type. Your docs still reference educationAssignmentPointsGradeType.

Accepted Answer

Based on the metadata (https://graph.microsoft.com/beta/$metadata), the correct namespace and type should be microsoft.graph.educationAssignmentGradeType. This also aligns with the JSON representation in the Graph documentation:

   json  
   {  
     "id": "String (identifier)",  
     "addedStudentAction": "none",  
     "addToCalendarAction": "string",  
     "allowLateSubmissions": true,  
     "allowStudentsToAddResourcesToSubmission": true,  
     "assignDateTime": "String (timestamp)",  
     "assignTo": {"@odata.type": "microsoft.graph.educationAssignmentRecipient"},  
     "assignedDateTime": "String (timestamp)",  
     "classId": "String",  
     "closeDateTime": "String (timestamp)",  
     "createdBy": {"@odata.type": "microsoft.graph.identitySet"},  
     "createdDateTime": "String (timestamp)",  
     "displayName": "String",  
     "dueDateTime": "String (timestamp)",  
     "grading": {"@odata.type": "microsoft.graph.educationAssignmentGradeType"},  
     "instructions": {"@odata.type": "microsoft.graph.itemBody"},  
     "lastModifiedBy": {"@odata.type": "microsoft.graph.identitySet"},  
     "lastModifiedDateTime": "String (timestamp)",  
     "notificationChannelUrl": "string",  
     "status": "string",  
     "webUrl": "string",  
     "resourcesFolderUrl": "string"  
   }

Answer

Same problem here:

"Invalid OData type specified: \"microsoft.education.assignments.api.educationAssignmentPointsGradeType\"",

},
"status": "draft",
"allowStudentsToAddResourcesToSubmission": true,
"assignTo": {
"@odata.type": "#microsoft.graph.educationAssignmentClassRecipient"
}
}

It is urgent for me too.
