Create assignment with `notificationChannelUrl` return error 400(20243 Notification channel url is invalid)

We can using the Education Graph API to create an edit assignments without "notificationChannelUrl" in request body.

Then we using endpoint: https://docs.microsoft.com/en-us/graph/api/resources/educationassignment?view=graph-rest-1.0#properties
to set the request body with notificationChannelUrl, and now return bad request with following error message.

error:{"code":"20243","message":"Invalid request body. Notification channel url is invalid."

API usage process：
1, use https://graph.microsoft.com/v1.0/teams/{eam-id}/channels, then get the channel list with ["webUrl"]=>
string(201) "https://teams.microsoft.com/l/channel/19%3azP ... ...,

   2, create assignments with "notificationChannelUrl": webUrl,

The question is: What url string I can set for notificationChannelUrl?

Thank you very much!

Hi @BrunoIT-3437

The notificationChannelUrl is not a hyperlink to the channel but the graph api used to get the channel.

 "notificationChannelUrl": "https://graph.microsoft.com/v1.0/teams/{team-id}/channels/{channel-id}"
