Firebase functions logger log is undefined

Question

const functions = require("firebase-functions");

functions.logger.log("Hello from info. Here's an object:", someObj);

So when I run functions.logger.log this is the error I get:

TypeError: Cannot read property 'log' of undefined

Why is logger undefined and how do I fix this?

Check your version of the firebase-functions module. The logger requires version 3.7.0 or later. The latest at the time of this writing is 3.13.0.
