Unsupported field value: a function (found in field creationTime)

user-profile.ts

export interface UserProfile {
    id: string;
    name: string;
    email: string;
    phone?: string;
    creationTime?: any;
}

service.ts

async signUp(name: string, email: string, password: string): Promise<void> {
    try {
      const user: firebase.auth.UserCredential = await this.afAuth.auth.createUserWithEmailAndPassword(email, password);
      const userProfileDocument: AngularFirestoreDocument<UserProfile> = this.fireStore.doc(`userProfiles/${user.user.uid}`);
      const userProfile: UserProfile = {
        id: user.user.uid,
        email: email,
        creationTime: firebase.firestore.Timestamp,
        name: name
      };
      await userProfileDocument.set(userProfile);
    } catch (error) {
    }
  }

One error on console:

[2019-02-28T08:01:58.804Z] @firebase/firestore: Firestore (5.8.3):
The timestampsInSnapshots setting now defaults to true and you no
longer need to explicitly set it. In a future release, the setting
will be removed entirely and so it is recommended that you remove it
from your firestore.settings() call now.

This is the next error:

FirebaseError: Function DocumentReference.set() called with invalid data.

You need to do as follows:

1st error: https://github.com/angular/angularfire2/issues/1993#issuecomment-456481677

2nd Error:

  const userProfile: UserProfile = {
    id: user.user.uid,
    email: email,
    creationTime: firebase.firestore.FieldValue.serverTimestamp(),
    name: name
  };

As explained in the doc, firebase.firestore.FieldValue.serverTimestamp() will return a "sentinel" object that you use when building the object to be written to Firestore. It will indicate to the server that it should replace it with an actual Timestamp.
