Well i got the same question as: https://stackoverflow.com/questions/38352747/google-classroom-test-account-does-not-have-google-drive-access
Is there any way to access Google drive on a Google Classroom test account?
This is the error when creating a assignment with a google drive file.
com.google.api.client.googleapis.json.GoogleJsonResponseException: 403 Forbidden
{
"code" : 403,
"errors" : [ {
"domain" : "global",
"message" : "The caller does not have permission",
"reason" : "forbidden"
} ],
"message" : "The caller does not have permission",
"status" : "PERMISSION_DENIED"
}
Well i fixed this by getting a real teacher/student account
