Getting 'The timestampsInSnapshots setting now defaults to true' firestore error in console

Go to your app.modules.ts file and add import:

import { FirestoreSettingsToken} from '@angular/fire/firestore';

Then add this value in your providers array:

providers: [{ provide: FirestoreSettingsToken, useValue: {} }]

In general, we configure firebase in our app in the following way:

firebase.firestore().settings({
    timestampsInSnapshots: true
});

For the above configuration, It shows the following warning:

In Order to resolve it, Just simply remove the timestampsInSnapshots attribute from the settings parameter. After fixing, your config should be changed to:

firebase.firestore().settings({});
