oauthenticator.awscognito.AWSCognitoAuthenticator could not be imported

ZackInNC · November 22, 2021, 12:18pm

I have 2 side-by-side ubuntu servers (EC2).

On one, I followed the vanilla install instructions, including SSL and Cognito integration, and it works as expected.

On the other, I did the same thing, except that the machine was already setup with python and a conda environment.

In the latter, when I try to use Cognito for authentication (specified below), I get this error:

python3[86637]: [C 2021-11-22 12:03:19.200 JupyterHub application:90] Bad config encountered during initialization: The ‘authenticator_class’ trait of <main.JupyterHub object at 0x7f28f60dcb50> instance must be a type, but ‘oauthenticator.awscognito.AWSCognitoAuthenticator’ could not be imported

Here’s how I setup the SSL and cognito integration:

sudo tljh-config set https.enabled true
sudo tljh-config set https.letsencrypt.emal me@me.com
sudo tljh-config add-item https.letsencrypt.domains
sudo tljh-config add-item https.letsencrypt.domains
sudo tljh-config reload proxy

create conf file:

sudo vi /etc/systemd/system/jupyterhub.service.d/jupyterhub.conf

With these contents:
[Service]
Environment=AWSCOGNITO_DOMAIN=

#create awscognito.py
sudo vi /opt/tljh/config/jupyterhub_config.d/awscognito.py

with these contents:
##############################################
Setup aws Cognito Authenticator
##############################################
AWSCognitoAuthenticator.client_id=‘abc’
AWSCognitoAuthenticator.client_secret=‘xyz’
AWSCognitoAuthenticator.oauth_callback_url=’’
AWSCognitoAuthenticator.username_key=‘email’
AWSCognitoAuthenticator.oauth_logout_redirect_url=’’

These instructions alone worked for the server that didn’t have conda and python setup in advance.

I also tried this, but everything was already installed:

pip install -U oauthenticator

I also tried updating the symlinks for python and pip under the the tljh install to point at the conda python installation - also to no avail.

Note that the first instance was installed several weeks ago, and is on python version 3.6.9 and the latter is on python version 3.8.8

Can anyone help me understand what I’m missing here?

My guess is that you’ve installed something into the wrong environment. Can you run conda list and pip list in all of your environments?

It looks like you’ve listed the default Python environment. With TLJH the hub environment is under /opt/tljh/hub.

Are you using the latest version of TLJH?

ZackInNC · November 27, 2021, 1:20pm

I believe so.

Does this look correct?

Is the authenticator installed in your hub environment?

Does not appear to be:

What does that mean (or imply)?

ZackInNC · December 9, 2021, 12:59pm

Looks like I have the same libraries on the machine that works and the machine that doesn’t - with the exception of jupyterhub-dummyauthenticator, but the versions are all different.

Machine that does NOT work:
(base) ubuntu@my-machine:~$ /opt/tljh/hub/bin/pip list | grep auth
jupyterhub-firstuseauthenticator 1.0.0
jupyterhub-ldapauthenticator 1.3.2
jupyterhub-nativeauthenticator 1.0.5
jupyterhub-tmpauthenticator 0.6
oauthenticator 14.2.0
oauthlib 3.1.1

Machine that DOES work:
jupyterhub-dummyauthenticator 0.3.1
jupyterhub-firstuseauthenticator 0.14.1
jupyterhub-ldapauthenticator 1.3.0
jupyterhub-nativeauthenticator 0.0.7
jupyterhub-tmpauthenticator 0.6
oauthenticator 0.10.0
oauthlib 3.1.1

ZackInNC · December 9, 2021, 1:23pm

Circling back with a solution:

I explicitly set the version for oauthenticator to 0.10.0:

sudo /opt/tljh/hub/bin/pip install ‘oauthenticator==0.10.0’

And then restarted the service and it worked correctly.

So it appears that TLJH is not compatible with the newer/latest version(s).
