Missing await (ARCH2029)

Key python.async.missing-await · Severity warning · Category async

Using a coroutine-returning call in a condition or value position without await means the coroutine never runs; because a coroutine object is always truthy, conditions evaluate true by accident.

Incorrect

async def process(user_id):
    if is_active(user_id):  # coroutine is always truthy, never runs
        await notify(user_id)

Correct

async def process(user_id):
    if await is_active(user_id):
        await notify(user_id)

Fix

Prefix coroutine-returning calls with await so the result is resolved before it is used.
