From the screen shot, it looks like you're running this on your local machine. The error message suggests that the environment variables that point to your credentials isn't setup.

See the Before you Begin section of the library documentation for how to setup that environment. One of the steps includes setting up authentication by downloading credentials and setting an environment variable to point to them. This will also set the project ID you're working with.
