Stuck with key error from flask tutorial

My config.py:

OPENID_PROVIDERS = [
{ 'name': 'Google', 'url': 'https://www.google.com/accounts/o8/id' },
{ 'name': 'Yahoo', 'url': 'https://me.yahoo.com' },
{ 'name': 'AOL', 'url': 'http://openid.aol.com/<username>' },
{ 'name': 'Flickr', 'url': 'http://www.flickr.com/<username>' },
{ 'name': 'MyOpenID', 'url': 'https://www.myoopenid.com' }
]

      

        
        
        
      

    

Views.py:

@app.route('/login', methods=['GET', 'POST'])
def login():
    form = LoginForm()
    if form.validate_on_submit():
        flash('Login requested for OpenID="' + form.openid.data
          + '", remember_me=' + str(form.remember_me.data))
        return redirect('/index')
    return render_template('login.html', 
        title='Sign In', 
        form=form,
        providers=app.config['OPENID_PROVIDERS'])

      

        
        
        
      

    

The tutorial lives here

Thanks for the help.
