How to get `Cloud Functions shell` work with Firestore

Question

Running:

firebase experimental:functions:shell

When I try to call my function like so:

sendEmail('data', {params: 'commentId:12'})

I get:

Info: Function crashed TypeError: Cannot use 'in' operator to search for 'exists' in data

How does one initiate the new onWrite on a Firestore triggered cloud function

With version 3.15.1 of the Firebase CLI, you can now run Firestore functions locally.
