Error: Cannot run the event loop while another loop is running when using async_notify_multiple_devices

fastapi = "^0.111.0"
pyfcm = "^2.0.4"
I using async_notify_multiple_devices and get error: Cannot run the event loop while another loop is running

[vmtniichov]

from pyfcm.async_fcm import fetch_tasks
from pyfcm.baseapi import BaseAPI


class FCMNotification(BaseAPI):

    async def send_async_request(self, params_list, timeout=5):
        payloads = [self.parse_payload(**params) for params in params_list]
        responses = await fetch_tasks(
            end_point=self.FCM_END_POINT,
            headers=self.request_headers(),
            payloads=payloads,
            timeout=timeout,
        )

        return responses

Create a new FCM class inherit from the BaseAPI and replace async_notify_multiple_devices usages with send_async_request will resolve your issue
