Cloud Functions for Firebase onWrite trigger: snapshot.val is not a function

Question

I created few functions in the same index.js file, which is sendEmail, sendEmailByDbStatusChange and sendEmailConfirmation.

Answer 1

Since version 1.0.0 of the firebase-functions module, database onWrite events now deliver a Change object rather than a DataSnapshot object as the first parameter. You can read about all the breaking changes in 1.0.0 in the documentation. You should use this change object instead to choose if you want to examine the contents of the database before or after the change that invoked it.
