Disabling flow control generates error: "Error while waiting for Protractor to sync with the page: "both angularJS testability and angular testability are undefined."

Here is my config:

exports.config = {
  capabilities: {
    'browserName': 'chrome'
  },
  seleniumAddress: 'http://localhost:4444/wd/hub',
  framework: 'jasmine',
  specs: ['test.spec.ts'],
  SELENIUM_PROMISE_MANAGER: false,
  jasmineNodeOpts: {
    defaultTimeoutInterval: 30000
  },	
  beforeLaunch: function () {
    require('ts-node/register')
  }
};

And here is my simple test:

import {
    browser,
    ExpectedConditions,
    $
} from 'protractor';

describe('When user click \"Test\" button', async () => {
  beforeAll(async () => {
    expect(browser.getCurrentUrl()).toContain('myawesomewebsite');
  });

  it ("should click the button", async () => {
    var button = $(".button");
    button.click();
  });
});

This throws me the following error:

UnhandledPromiseRejectionWarning: Error: Error while waiting for Protractor to sync with the page: "both angularJS testability and angular testability are undefined.  This could be either because this is a non-angular page or because your test involves client-side navigation, which can interfere with Protractor's bootstrapping.  See http://git.io/v4gXM for details"

However it works great if I set SELENIUM_PROMISE_MANAGER to true.

According to the simplicity of this test, this seems to be a bug with protractor itself, am I wrong?

you have to add .waitForAngularEnabled(false) in the onPrepare property of protractor.conf:

onPrepare: async () => {
    await browser.waitForAngularEnabled(false);
    ...
}

@Kurt29 is the page per chance Unicode encoded somehow and has the setting <meta charset="utf-8" /> in the head?

I’m sitting with the same problem.
