inject() must be called from an injection context

I am trying to export my Angular app as an npm module to be consumed by other applications, but am running into some difficulties. I have not been able to find this error anywhere else on the internet, and am at my wit's end.

I followed this tutorial: https://medium.com/@nikolasleblanc/...h-the-angular-cli-and-ng-packagr-53b2ade0701e

I used ng-packagr to export my app as an npm module. I can successfully install it from a local folder on a barebones test app, but cannot get it to display my app.

Error:

Any help or pointers at all would be appreciated, thank you.
