Getting build error after installing the @ember/test-helpers package

Am using the ember-a11y-testing(v4.0.8) add-on, which is enforcing the peer dependency of @ember/test-helpers >= 2.0.0. After installing the @ember/test-helpers(v2.2.6), my build is getting error.

Ember - v3.16.2, Node - v12.18.0
