Plotly OAuth auth.logout() Issue

Dash Python
1

There seems to be an issue with the implementation of the Plotly OAuth auth.logout() function.

The issue shows up when running:

import dash
import dash_auth
import dash_html_components as html
import os

os.environ['PLOTLY_USERNAME'] = '<your_username>'
os.environ['PLOTLY_API_KEY'] = '<your_api_key>'

APP_NAME = 'app_name'
APP_URL = 'http://127.0.0.1:8050/'
external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']
app = dash.Dash(__name__, external_stylesheets=external_stylesheets)
server = app.server

auth = dash_auth.PlotlyAuth(app, APP_NAME, 'private', APP_URL)

app.layout = html.Div([
    html.Div('TEST', id='div'),

    auth.create_logout_button(
            label='Sign out',
            redirect_to='https://google.com')
])

if __name__ == '__main__':
    app.run_server(debug=True)

Here is the debug:
