Describe the bug Running the elyra/elyra:3.14.3 image on docker and having installed the jupyterlab-s3-browser using the guide in the readme-file I get an empty widget.

1. Install container on docker: docker run -p 8888:8888 elyra/elyra:3.14.3
2. Open elyra on localhost http://127.0.0.1:8888/lab
3. Open a terminal in the elyra interface.
4. Install browser plugin with pip install jupyterlab-s3-browser
5. enable browser plugin with jupyter serverextension enable --py jupyterlab_s3_browser
6. Reload page

I get an empty widget instead of the bucket config UI i expected.

In the container i can see the following lines:

[W 2023-03-14 14:31:39.683 ServerApp] 404 GET /api/me?1678804299678 (192.168.255.1) 2.07ms referer=http://127.0.0.1:8888/lab
[W 2023-03-14 14:31:40.833 ServerApp] 404 GET /jupyterlab_s3_browser/auth?1678804300830 (192.168.255.1) 1.54ms referer=http://127.0.0.1:8888/lab

Expected behavior A UI letting me put in credentials for bucket storage.

**Desktop **

• OS: Windows 10
• Browser chrome / edge
• Version of jupyterlab-s3-browser extension: 0.10.0

Has there been a breaking change version regarding the elyra/jupyter api?

After some research it looks like one of the jupyterlab-s3-browser dependencies has a breaking change. Cryptography has removed the method OpenSSL_add_all_algorithms in the 39.0.0 version. https://cryptography.io/en/latest/changelog/#v39-0-0

I fixed this by installing cryptography 38.0.4 with

RUN  pip install cryptography==38.0.4
RUN  pip install jupyterlab-s3-browser 
RUN  jupyter serverextension enable --py jupyterlab_s3_browser

OR, probably prefered solution

RUN  pip install pyopenssl --upgrade
RUN  pip install jupyterlab-s3-browser 
RUN  jupyter serverextension enable --py jupyterlab_s3_browser

Hope that helps.

@paah-scb Tried your suggestion (jupyterLab Version 3.0.16). Still no result. Continues to show empty widget.

@KrishnaPG ,

Try to install this version of the exntension

jupyterlab-s3-browser==0.11.1

and in case the problem still persists, add this version of boto3 -> boto3==1.17.106

Seeing this same issue when trying to use the jupyterlab-s3-browser (v0.12.0) extension in JupyterLab (v4.0.3)

1. Installed JupyterHub in Kubernetes using the Zero to JupyterHub Helm charts helm install hub jupyterhub/jupyterhub -f config.yaml
2. Opened JupyterLab on localhost http://localhost/user/edgardo%20antuna/lab
3. Opened Terminal in JupyterLab interface
4. Install browser plugin with pip install jupyterlab-s3-browser
5. Enable browser plugin with jupyter serverextension enable --py jupyterlab_s3_browser
6. Reload page

I am also getting an empty widget instead of the expected widget contents

When inspecting the network console I am also seeing the 404 HTTP Errors

I tried the suggestions in this thread, like downgrading the cryptography==38.0.4 and jupyterlab-s3-browser==0.11.1 versions, but no luck. Getting the same result.

pip install cryptography==38.0.4
pip install jupyterlab-s3-browser 
jupyter serverextension enable --py jupyterlab_s3_browser

pip install jupyterlab-s3-browser==0.11.1
jupyter serverextension enable --py jupyterlab_s3_browser

Expected behavior The "Object Storage Browser" shows the expected contents shown in the README file.

Environment

• Tested both in AWS EKS and local desktop Minikube Kubernetes
• OS: Red Hat Enterprise Linux
• JupyterLab Version 4.0.3
• Browser Chrome version 118.0.5993.71 (Official Build) (64-bit)
• Version of jupyterlab-s3-browser extension: 0.12.0 & 0.11.1

Is this issue due to an incompatibility between the latest jupyterlab-s3-browser extension (v0.12.0) and JupyterLab (v4.0.3)?
