TypeError: Object Cannot Be Used in Await

TypeError: object NoneType can't be used in 'await' expression

Quick Answer

You are awaiting a non-awaitable object. Only coroutines, Tasks, and Futures can be awaited. Check that the function is defined with async def.

Why This Happens

The await keyword only works with awaitable objects. If you await a regular function's return value, Python raises TypeError.

The Problem

def fetch():  # Not async!
    return 'data'

async def main():
    result = await fetch()

The Fix

async def fetch():  # async!
    return 'data'

async def main():
    result = await fetch()

Step-by-Step Fix

  1. 1

    Check function definition

    Verify the function uses 'async def'.

  2. 2

    Check return values

    Ensure the method returns an awaitable.

  3. 3

    Use asyncio.to_thread()

    Wrap sync functions: await asyncio.to_thread(sync_func).
