Error typeerror object is not a function at new angularfiremessaging

A Firebase error!

The error TypeError: Object is not a function typically occurs when you're trying to use an object as a function. In this case, it seems like you're trying to create a new instance of AngularFireMessaging using the new keyword, but AngularFireMessaging is not a function.

Here are a few possible solutions:

1. Check your imports: Make sure you've imported AngularFireMessaging correctly in your Angular module. You should have something like this:

   import { AngularFireMessaging } from '@angular/fire/messaging';

2. Verify the module is loaded: Ensure that the @angular/fire/messaging module is loaded in your Angular application. You can do this by checking the console for any errors or by using the Chrome DevTools to inspect the module loading process.
3. Check the version: Make sure you're using a compatible version of @angular/fire/messaging. You can check the version by running npm ls @angular/fire/messaging or yarn ls @angular/fire/messaging. If you're using an outdated version, try updating to the latest one.
4. Check the Firebase configuration: Ensure that your Firebase configuration is correct and that you've initialized the Firebase app correctly in your Angular application. You can check the Firebase documentation for more information on how to do this.
5. Try a clean install: Sometimes, a clean install of the @angular/fire/messaging module can resolve the issue. Try running npm uninstall @angular/fire/messaging or yarn uninstall @angular/fire/messaging, then npm install @angular/fire/messaging or yarn add @angular/fire/messaging.

If none of these solutions work, please provide more details about your project, including your Angular version, Firebase version, and any relevant code snippets. I'll do my best to help you troubleshoot the issue!
