I am getting the below exception
"error": {
"code": "OrganizationFromTenantGuidNotFound",
"message": "The tenant for tenant guid '****' does not exist.",
"innerError": {
"request-id": "2acd6af1-99f8-4aab-b71d-cffc60263a05",
"date": "2019-04-20T11:33:04"
}
while updating the group using open extension as shown below: -
POST https://graph.microsoft.com/v1.0/groups/db5f4dbe-40e0-4352-84fb-9a20c131cfaf/extensions HTTP/1.1
Authorization: Bearer ****
Content-Type: text/plain; charset=utf-8
Host: graph.microsoft.com
Content-Length: 111
Expect: 100-continue
Connection: Keep-Alive
{ "#odata.type":"microsoft.graph.openTypeExtension","extensionName":"com.test.nickName","date":"OpenExtension"}
I am using user***#outlook.com id and having active azure subscription. I have given all delegated permission to microsoft graph.

Answer 1

Content type was not specified and it was going as text. Error handling could be improved. After changing content type to "application/json", it is working perfectly fine.
