Hello. I'm have self hosted Revolt server and try write bot for it. But example code, with custom api_url doesn't work with error:

Traceback (most recent call last):

Code of main.py:

import revolt
import asyncio


class Client(revolt.Client):
    async def on_message(self, message: revolt.Message):
        if message.content == "hello":
            await message.channel.send("hi how are you")


async def main():
    async with revolt.utils.client_session() as session:
        client = Client(session, "bot-token",
                        api_url="http://self-hosted/api")
        await client.start()

asyncio.run(main())

This seems like a configuration issue on the third-party instance, please insure the websocket url given from the api is correct.
