Updating ESA from 2.0 to 2.1.0 fails to authenticate

I updated ember-simple-auth (ESA) to 2.0 version as explained its Migration section for 2.0. version and removed application.js authorizer:

# adapters/application.js

export default JSONAPIAdapter.extend(DataAdapterMixin, {
  host: config.apiHost,

  authorize(xhr) {
    let { access_token } = this.get('session.data.authenticated');
    if (isPresent(access_token)) {
      xhr.setRequestHeader('Authorization', `Bearer ${access_token}`);

  // allows the multiword paths in urls to be underscored
  pathForType: function(type) {
    let underscored = underscore(type);
    return pluralize(underscored);

Authentication continued to work as needed. Then suddenly it was reported that the file upload was broken. After analyzing, I discovered that ESA version 2.1.0 I updated to recently, set the application adapter differently:

headers: computed('session.data.authenticated.access_token', function() {
    let headers = {};
    if (this.get('session.isAuthenticated')) {
      headers['Authorization'] = `Bearer ${this.get('session.data.authenticated.access_token')}`;

    return headers;

As you see, there is no more authorize method. And the ember-active-storage uses this new way for authenticated headers. When I replace the authorize method with headers CP, I fail to pass the authentication, the browser is running in an endless loop…

When using the previous working ESA version, here is what I have in the Local Storage:


Nothing at all with the latest implementation that uses headers. What’s wrong with that? Even ESA dummy app uses the same implementation. Any idea? Thank you.
