Export "getInstance" was not found in "amplitude-js"

[bureaug]

Summary

I have been using amplitude with Angular up to V11 with no problems. After upgrading to Angular 15.2.9 and trying to compile the project I get the following error:

./libs/***/analytics.service.ts:6:22-43 - Error: export 'getInstance' (imported as 'amplitude') was not found in 'amplitude-js' (possible exports: default)

./libs/***/analytics.service.ts:40:25-43 - Error: export 'Identify' (imported as 'amplitude') was not found in 'amplitude-js' (possible exports: default)

The analytics.service.ts looks like this:

import { Injectable } from '@angular/core';
import * as amplitude from 'amplitude-js';

@Injectable()
export class AnalyticsService {

	private amInstance = amplitude.getInstance();
        [...]

Here is an excerpt from my package.json

	"dependencies": {
		"@angular/animations": "15.2.9",
		"@angular/cdk": "15.2.9",
		"@angular/common": "15.2.9",

Thanks for any tips!
