Firebase cloud messaging topics not functional in emulator

vidicunt commented 2 years ago

Hello! I'm trying to test FCM using firebase emulator, however it isn't functional. For instance:

const message = {
  data: {
    info: "myInfo"
    },
  topic: "myTopic"
};

await admin.messaging().send(message)

This shows an error in the console:


>  var _this = _super.call(this, errorInfo.message) || this;
>                             ^
>

Note, this only happens for FCM topics. I am using the emulators on a Windows 10 machine.

The Emulator Suite does not support FCM (yet). Is it possible you're getting the error because the code is talking to the production server? If a FCM emulator is what you want, please open a feature request instead.

Go to google cloud then go to API and Services then Enabled API and Services then turn on the cloud messaging Turn on Firebase cloud messaging API.

firebase / firebase-tools
