WSGI is unable to acces plotly files as required thus, the whole app falls apart.

Instead of using the credentials files, which the IIS user doesn’t have access, can you try putting your keys in environ vars ?

The env vars you need:

PLOTLY_USERNAME
PLOTLY_API_KEY

And maybe those if you need the .configs file.

PLOTLY_DOMAIN
PLOTLY_API_DOMAIN

3

Can you please give an example of where I can find the files to update these ENV variables?

4

The files are in ~/.plotly.

Thanks Phillippe, i dont see a place in the .config or .credential files for environ vars. Where am I supposed to update the ENV variables?

You don’t update them in a file, you have to set like so:

Linux:
$ export PLOTLY_USERNAME=my-username

Windows:

setx PLOTLY_USERNAME=my-username

Python:

import os

os.environ['PLOTLY_USERNAME'] = 'my-username'

thanks Philippe.

My app.py file has the following

import dash

from dash.dependencies import Input, Output

import dash_core_components as dcc

import dash_html_components as html

import plotly.graph_objs as go

import pandas as pd

import os

import plotly

plotly.tools.set_credentials_file(username=“jabrown10”, api_key=“pFozcI42TMpXne3vGBoE”)

import plotly.plotly as py

py.sign_in(“jabrown10”, “jv281316N”)

os.environ[‘PLOTLY_USERNAME’] = ‘********’

os.environ[‘PLOTLY_API_KEY’] = ‘xxxxxxxxxxxxxxxxxx’

os.environ[‘PLOTLY_DOMAIN’] = ‘https://plot.ly’

os.environ[‘PLOTLY_API_DOMAIN’] = ‘https://api.plot.ly’

and I also set the above keys as Environment variables on my system but I continue to get the same error

You need to remove the plotly.tools.set_credentials_file(username=“xx”, api_key=“xx”), setting them on the system is the right way to do it and you can remove the os.environ part if you do.

Thanks That did the trick!
