Microsoft Teams Graph API - Invalid bind property name owners in request - microsoft-graph-api

Question

I'm currently having major issues with creating teams from the Graph API. I was initially trying to create teams based on groups, however I have found out today that you can now create a team without creating a group first then waiting 15 minutes to then create the team from the following link. This would make things considerably simpler.
https://learn.microsoft.com/en-us/graph/api/team-post?view=graph-rest-1.0
I am using the Microsoft.Graph SDK (v3.12.0 released 26th Aug) so replicated the http call using the SDK as follows.
var team = new Team
{
DisplayName = "My Group Name",
Description = "My Group Description",
AdditionalData = new Dictionary<string, object>()
{
{"template#odata.bind", "https://graph.microsoft.com/v1.0/teamsTemplates('educationClass')"},
{"owners#odata.bind", $"[\"https://graph.microsoft.com/v1.0/users('{usersGuid}')\"]"}
},
};
var response = await _graphClient.Teams
.Request()
.AddAsync(team);
The code above gives a:
[16:14:01 ERR] An unhandled exception has occurred while executing the request.
Status Code: BadRequest
Microsoft.Graph.ServiceException: Code: BadRequest
Message: Invalid bind property name owners in request.
If I remove the line
{"owners#odata.bind", $"[\"https://graph.microsoft.com/v1.0/users('{usersGuid}')\"]"}
from the code I get the following:
ErrorMessage : {"errors":[{"message":"A team owner must be provided when creating a team in application context."}]
Any advice would be greatly appreciated.
Thanks,
Nick

In v1.0 the owners relationship is not currently present, so you have to use the beta endpoint.
POST: https://graph.microsoft.com/beta/teams
with the following body format
{ "template#odata.bind":"https://graph.microsoft.com/beta/teamsTemplates('standard')", "displayName":"Test Team", "description":"Test description", "owners#odata.bind":["https://graph.microsoft.com/v1.0/users/{user guid}"] }
Note: the user guid should also be bare, i.e without the brackets and quotes in your example.
