Angular - lesson 8 - deploy to firebase [error no default ex

First of all, this walkthrough / lesson guide is amazing! I've learned so much already. Secondly, here's the issue I'm having. lol

I received this error:

idb.services.ts ERROR: idb/lib/idb has no default export

While trying to complete this step:

After initializing the application we have nothing else left to do but to send it to the Firebase servers. But first we have to build a production version of our application! To do this, run the command below in the terminal of your application.

npm run pwa

This is the section of the Angular Lesson that I'm having an issue with:
