Hi, I’m trying to add basic dash authentication following this tutotrial > **[Authentication | Dash for Python Documentation | Plotly](https://dash.plotly.com/authentication)** > > Protect your apps behind a login screen and access user authentication data in your Dash apps. And upon doing so getting the following error locally: > Traceback (most recent call last): > File “index.py”, line 13, in > from appc import app, server > File “C:\Users\USER\Desktop\Folder\SubFolder\appc.py”, line 31, in > APP\_URL > File “C:\Users\USER\Anaconda3\lib\site-packages\dash\_auth\plotly\_auth.py”, line 37, in **init** > salt=app\_name > File “C:\Users\USER\Anaconda3\lib\site-packages\dash\_auth\oauth.py”, line 24, in **init** > Auth. **init** (self, app) > File “C:\Users\USER\Anaconda3\lib\site-packages\dash\_auth\auth.py”, line 10, in **init** > self.\_index\_view\_name = app.config[‘routes\_pathname\_prefix’] > TypeError: ‘type’ object is not subscriptable Please note that without authentication my web app runs locally and on Heroku without an issue. It’s a multipaged app so i’ve segmented it into different files. `index.py` imports `'app'` and `'server'` from `appc.py` file. * * * > Traceback (most recent call last): > File “index.py”, line 13, in > from appc import app, server > File “C:\Users\USER\Desktop\Folder\SubFolder\appc.py”, line 31, in > APP\_URL > File “C:\Users\USER\Anaconda3\lib\site-packages\dash\_auth\plotly\_auth.py”, line 37, in **init** > salt=app\_name > File “C:\Users\USER\Anaconda3\lib\site-packages\dash\_auth\oauth.py”, line 24, in **init** > Auth. **init** (self, app) > File “C:\Users\USER\Anaconda3\lib\site-packages\dash\_auth\auth.py”, line 10, in **init** > self.\_index\_view\_name = app.config[‘routes\_pathname\_prefix’] > TypeError: ‘type’ object is not subscriptable Above error is seen on trying to use PlotlyAuth authentication method.

Any help appreciated. Thanks ---

> [@gillmonii](#): > > dash.ly 0.17.3 This isn’t right - I’d try uninstalling this package, it was left over from a previous era. ---

Hi. I also had this error and found out I had dash.ly installed in my base environment so, although it wasn’t showing up in pip list, it was still breaking app.config. When I uninstalled dash, dash.ly, flask, and whole bunch of other stuff from my base env it worked perfectly. I guess I must have installed in base before I learned better habits… So the lesson I learned is: Keep your base env lean and clean 😃 ---

You don’t even have dash-auth, and the topic is about dash authentication. ?? ---

Wow you are right! So dumb of me. I never updated the requirements.txt to include the dash-auth. You dont have to be so rude tough, everyone make mistakes. Thanks. ---

Apologies, I was just confused by your post.
