Question BadRequest (21400)

Hey, I'm trying to use the matchmaker, but when I create a backfill ticket I get this response:

[Matchmaker]: BadRequest (21400)

Title: Bad Request

Errors:

{"source":["Value cannot be null. (Parameter 'source')"]}

I've tried looking around but cannot find the "source" parameter that it is referring to.

The code creating the ticket looks like this:

Code (CSharp):

1.             BackfillTicketId = await MatchmakerService.Instance.CreateBackfillTicketAsync(new ()
2.             {
3.                 Connection = $"{transport.ConnectionData.Address}:{transport.ConnectionData.Port}",
4.                 Properties = new BackfillTicketProperties(new MatchProperties(players: currentPlayers)),
5.                 QueueName = payload.QueueName,
6.                 MatchId = payload.MatchId,
7.                 PoolId = payload.PoolId,
8.             });

Any help getting this resolved would be great!

 

Turns out removing the MatchId and PoolId makes it work
