RaiseEventAsync throws Grpc.Core.RpcException

[Fazer01]

When RaiseEventAsync("NonExistantId", "SomeEvent1", "SomeData");' is called in the HttpTrigger below, we receive an exception of type Grpc.Core.RpcExceptionwith the message:Status(StatusCode="Unknown", Detail="Exception was thrown by handler.")`

Errormessage:
[2024-10-23T09:25:13.418Z] Host lock lease acquired by instance ID '000000000000000000000000430AE0B1'.

Example
Example of HttpTrigger used. The catch implementation is just a default here to see in the debugger what kind of exception is thrown:

  [Function(nameof(FireEvent1))]
    public async Task<HttpResponseData> FireEvent1([HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = "trigger/event1")] HttpRequestData request, 
        [DurableClient] DurableTaskClient client)
    {
        _logger.LogDebug("Firing event from trigger: '{trigger}'", nameof(FireEvent1));

        try
        {
            await client.RaiseEventAsync("NonExistantId", "SomeEvent1", "SomeData");//Constants.OrchestratorInstanceId, Constants.Event1, "Some data from event 1");
        }
        catch (Exception e)
        {
            Console.WriteLine(e);
            throw;
        }
       
        return request.CreateResponse(HttpStatusCode.OK);
    }

The documentation of the .RaiseEvent as stated here says the following:
Raised events for a completed or non-existent orchestration instance will be silently discarded.

That is obviously not the case. Some other folks have the same issue. Check this issue
