Not decoding from Base64Url encoding.

[delasteve]

Base64Url encoding contains - and _ instead of + and /, respectively. To account for this, a string replace is necessary. After looking through the codebase, I think I found where the culprit is.

angular-oauth2-oidc/angular-oauth2-oidc/src/base64-helper.ts

Lines 2 to 6 in 7e918f1

	export function b64DecodeUnicode(str) {
	return decodeURIComponent(atob(str).split('').map(function(c) {
	return '%' + ('00' + c.charCodeAt(0).toString(16)).slice(-2);
	}).join(''));
	}

It looks like you will need to do this prior to the decoding:

var base64 = str
  .replace(/\-/g, '+')
  .replace(/\_/g, '/');
