How to run a discord.py bot with FastAPI

fastapi-discord.py

import asyncio
import discord
from fastapi import FastAPI

app = FastAPI()
client = discord.Client()


# where the magic happens
# register an asyncio.create_task(client.start()) on app's startup event
#                                        ^ note not client.run()
@app.on_event("startup")
async def startup_event():
  asyncio.create_task(client.start('token'))


@app.get("/")
async def read_root():
  return {"Hello": str(client.user)}

@djalo you can try to setup and initialize the async loop before starting anything so they would most likely run on the same loop. If FastAPI creates its own loop it will not solve any thing though. This helped me to go through the same issue when running FastAPI with a mix between sync and async methods and google Firebase client in async mode.

        loop = new_event_loop()
        set_event_loop(loop)

Thanks for Your input! Gonna save this for another occasion.
I solved that pretty easily. Switched to discord.py library just because was curious.
No more errors, maybe that will help somebody too
