sometime reload function failed in loop

I am using playwright asynchronously within fastapi.

async def loop():
    while true:
        await page.reload()
        await asyncio.sleep(10)

@app.post("/test")
async def test():
     asyncio.create_task(loop())

When using the code above, an error occurs within a few hours.

this is full error message

Task exception was never retrieved

How can i solve this?
