Thanks in advance

Hi @Sra1T - Are you using Python3? The current release doesn’t support Python 3 right now. I’ll make a new release today that does.

chriddyp · August 17, 2017, 2:25pm

I have just upgraded the dash-auth package to 0.0.4. Upgrade with pip install dash-auth==0.0.4

Hi @chriddyp - thanks for responding,
but I still run into the same problem,

here is the error I get:

Thanks for reporting @Sra1T! Fixed this in https://github.com/plotly/dash-auth/pull/3, could you give it a try with v0.0.5? pip install dash-auth==0.0.05. Thanks!

Sra1T · August 22, 2017, 5:52am

Thanks @chriddyp!, It worked

natisanga · August 29, 2018, 10:50pm

I have had all sort of problems with the dash auth module. WHen it works locally and then I deploy into aws it does not work, I have seen two scnearios, one where the username/passworkd are asked for repeately and one where only a page saying Login Required is displayed.

I have checked I dont have plot.ly installed ( as seen on other threads) and have both the latest version of dash and dash_auth.

Any ideas?

I dont mind paying for the authentication via plotly but it does not work either. see next post

natisanga · August 29, 2018, 11:00pm

I also tried the
dash_auth.PlotlyAuth, but I also get an error. Any advice on how to test this locally before deploying…

anyway I went ahead and deployed an app in AWS and got the following error

[Thu Aug 30 00:22:48.063245 2018] [:error] [pid 3414] [remote 172.31.33.43:20] KeyError: ‘index’

I am not sure what the requirements are… I just copied the example on the website and installed the suggested versions

pip install dash==0.17.8rc2
pip install dash-auth==0.0.4

what are the actual requirements? what am I missing ?

Also it is not clear to me how I link the authorisation part of my app with my paid sucription with plotly

thanks!

UPDATE: I get the same error if I upgrade all packages

This is a really old version of dash-auth, please try with the latest: 1.1.2

Kelvin · June 7, 2019, 5:51pm

I met the same problem. How did you solve it?
