InvalidOperationException for async path

[emrys90]

I have an async route defined like this

mainRouter += new Route(RouteMethod.Post, "/online-player-update", OnlinePlayerUpdate);

And the method is defined like this

private async Task<HttpResponse> OnlinePlayerUpdate(HttpRequest request)

The route is actually called and appears to function correctly, but then the status return is a failure with an exception thrown of

System.Exception: [1543.85 ExceptionWriter.Write:365] Exception thrown at Fri, 02 May 2025 00:25:22 GMT
System.InvalidOperationException: Action of type "System.Runtime.CompilerServices.AsyncTaskMethodBuilder`1+AsyncStateMachineBox`1[[Sisk.Core.Http.HttpResponse, Sisk.Core, Version=0.15.2.0, Culture=neutral, PublicKeyToken=null],[ProjectCards.Networking.ServerRestApi+<OnlinePlayerUpdate>d__7, GameServer, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null]]" doens't have an action handler registered on the router that issued it.
   at Sisk.Core.Http.HttpServer.ListenerCallback(IAsyncResult result) + 0xadd

Any ideas how to fix this?

I realized this was happening because I was on an old version of Sisk that didn't support async yet. Updating fixed this issue.
