Code Error : asyncio.run() cannot be called from a running event loop

[Ivan-Keli]

Using the Fast-F1 signalr client?

I got this error while trying to demonstrates the usage of the SignalRClient.
Could you guys help me fix it

This is what i got when i tried using ChatGPT 3.5

The error message suggests that you are trying to run asyncio.run() within an already running event loop, which is not allowed. The asyncio.run() function is meant to be used in the context of a standalone script or application, and it creates a new event loop.

In your case, it seems like the SignalRClient is trying to start its own event loop, and there's already an existing event loop, leading to the RuntimeError.

To resolve this issue, you can try one of the following approaches:

1. Use asyncio.create_task() instead of asyncio.run():
   Replace the line asyncio.run(self._async_start()) with asyncio.create_task(self._async_start()). This will schedule the coroutine to run in the existing event loop.

   asyncio.create_task(self._async_start())

2. Run the event loop explicitly:
   If you have control over the main script or application, you can run the event loop explicitly. You would remove the call to client.start() and add the following:

   loop = asyncio.get_event_loop()
   loop.run_until_complete(client._async_start())

Choose one of these approaches based on your application structure and requirements.

I've converted this to issue #521. This problem is specific to running inside a Jupyter Notebook. Therefore, it also has somewhat low priority to be fixed.
