Unable to subscribe to events with multiple parameters

[andreasimeonegroovejones]

Describe the bug
When subscribing on a SignalR method with multiple parameters, I get an error and the message is not processed correctly.

To Reproduce

# method to be called once we receive the event ObjectDetectionData from the server with playerX, playerY, ballX, ballY
def ObjectDetectionData(playerX, playerY, ballX, ballY):
    print("Player position: (", playerX, ", ", playerY, ")")
    print("Ball position: (", ballX, ", ", ballY, ")")
    pass

hub_connection.on("ObjectDetectionData", ObjectDetectionData)

This is what the server is sending (Using .Net)

    public async Task ObjectDetectionData(float playerX, float playerY, float ballX, float ballY)
    {
        await Clients.All.SendAsync("ObjectDetectionData", playerX, playerY, ballX, ballY);
    }

Expected behavior
The 2 strings with the received data should appear in the terminal

Desktop (please complete the following information):

• OS: Windows
• Browser (no browser: server is dotnet8, client is python 3.7)
• Version latest, 0.9.5
