So I'm working on a firebase cloud messaging web app and getting the error:
Error: TypeError: messaging.getToken is not a function
I tried a lot to troubleshoot it, searched on google too, but no luck. I'd be thankful if someone can help me.
The same code is working fine in the official google example. Below is the line where I'm getting this error:
return messaging.getToken();

Reset to default 4Got it, I had to import getToken method also. Below is the new snippet which I should have wrote:
import { getMessaging, getToken } from "https://www.gstatic./firebasejs/9.0.2/firebase-messaging.js";
instead of:
import { getMessaging } from "https://www.gstatic./firebasejs/9.0.2/firebase-messaging.js";
import { getMessaging, getToken } from "https://www.gstatic./firebasejs/9.0.2/firebase-messaging.js";
const messaging = getMessaging(app);
// Add the public key generated from the console here.
getToken({vapidKey: "BBxqsbhYwDSfJ..."});
https://stackoverflow./a/70046707/5681567 Check out the link given. Same problem was arises with react native. Try this kind of thing
messaging ().getToken()
