Hi All,
I am trying to do Trailhead module about Heroku Connect module 
The application's server.js file in the root directory contains the server-side Node.js application. If you edit that file, you see the SQL statement used to update the database:UPDATE salesforce.Contact SET Phone = $1, MobilePhone = $1 WHERE ...
I couldn't find any such file containing the UPDATE salesforce.Contact SET Phone = $1, MobilePhone = $1 WHERE ... 
 please help
