I tried to scan an application with an authentication form created by Javascript (ReactJS framework). Arachni does not succeed to login to the application, gere the ruby script I used :

browser.goto 'https://***********.com/''screen1.jpg')
browser.text_field(:id => 'username' ).set '****'
browser.text_field(:id => 'password' ).set '****'
browser.element(:id => 'confirm-login' ).click'screen2.jpg')

framework.options.session.check_url = browser.url
framework.options.session.check_pattern = 'pattern'

It's a simple authentication flow (no SSO login or Federation system). Here the logs output from Arachni :

Session: [Watir::Exception::UnknownObjectException] unable to locate element, using {:id=>"username", :tag_name=>"input or textarea", :type=>"(any text type)"}

The "screen1.jpg" does not print the authentication form, only the background of the webpage is present. I tried to add a sleep(x) or a waitForElement just after the goto but the scan does not work either.

Here the source code when I inspect the web page (with chrome/firefox):

<form id="login-form">
  <div><!-- react-empty: 5 -->
      <div class="form-group">
        <label class="control-label h5"><span>email address</span></label>
          <input type="email" value="" name="username" autocomplete="email" id="username" class="form-control">
      <div class="form-group">
        <label class="control-label w100 h5"><span>Password</span></label>
        <input type="password" value="" name="password" autocomplete="current-password" id="password" class="form-control">
      <a class="small" href="/forget"><span>Forgot your password ?</span></a>
  <button id="confirm-login" type="submit" class="btn-block btn-success btn btn-primary" style="margin-top: 10px;"><span>Login</span></button>

Javascript is necessary to visit the webpage and to have access to the authentication form.

Have you an idea to fix this situation and succeed to scan this aplication ?

    I had similar problems with my script before. Not as a fix, but rather as a suggestion, I can advise to add some sleeps commands. Try below approach and let us know if that helps
    sleep 2
    browser.goto 'https://********.com/'
    sleep 2'screen1.jpg')
    browser.text_field(:id => 'username').wait_until_present
    browser.text_field(:id => 'username' ).set '
    browser.text_field(:id => 'password').wait_until_present
    browser.text_field(:id => 'password' ).set '
    browser.element(:id => 'confirm-login' ).click'screen2.jpg')

    Another approach will be to check there is only one unique id of 'username' on the page.

    That could work sometimes but this is the proper way to wait for elements:
