Hi @Deeptrentium, thanks for reaching out to us. I tried replicating, but I wasn't able to reproduce the error. If I can replicate the issue, I can have a better look into it. Please share a minimal, but complete sample of a project that I can run locally.

The JS SDK version of Firebase Cloud Messaging isn't supported in React Native: https://firebase.google.com/docs/web/environments-js-sdk

In order to use Firebase Cloud Messaging in React Native, you'd have to use the React Native Firebase library: https://rnfirebase.io/ Unfortunately, it doesn't work with Expo Go. I'm not sure if you're using Expo Go or just Expo, but since most Expo users use Expo Go I'm guessing you are too.

If that's the case, your only solution is to stop using Expo (or at least Expo Go), or stop using Firebase Cloud Messaging. Sorry, I know Firebase SDK support isn't really ideal for Expo users, but there's not a lot we can do at the moment (the FCM web SDK relies heavily on web APIs which React Native doesn't have).

@jbalidiong here is the sample project https://github.com/Deeptrentium/firebase-cloud-messaging where I face the issue run this project on web and click on notification button

let me know if you want more information

@Deeptrentium As mentioned above, the Firebase JS SDK doesn't support Cloud Messaging in React Native. I've described your options in the comment above, and I'm sorry we can't provide any better ones.
