Render the timestamp

[MincePie]

The helper in the article is:

/* helpers */
this.fieldValue = app.firestore.FieldValue;

(note - uppercase FieldValue)

Then in messages, you use:

          createdAt: this.props.firebase.fieldValue.serverTimestamp(),

This gives:

FirebaseError: Function DocumentReference.set() called with invalid data. Unsupported field value: undefined (found in field createdAt)

I have tried uppercasing as:

          createdAt: this.props.firebase.FieldValue.serverTimestamp(),

This gives:

TypeError: Cannot read property 'serverTimestamp' of undefined

In each case, the timestamp does not work.

How do I do I record and display a date?

A solution that works was finally found and is recorded here. I don't understand it but am EXHAUSTED from focusing on this problem.
