500 error for Theia IDE

[vnijs]

Just tried out the Theia IDE extensions which looks really interesting. Unfortunately I got a 500 error. The developer console shows the following:

Could you post a link to reproduce this (if it was on mybinder.org) or more details on your setup if this was a local error?

[vnijs]

Thanks for following up @betatim. Below the information to reproduce. If you need any additional information please let me know.

Docker file:

FROM vnijs/rsm-msba:latest
MAINTAINER Vincent Nijs "radiant@rady.ucsd.edu"
RUN pip3 install jupyter-theia-proxy
EXPOSE 8080 8787 8989 8765
CMD ["/usr/bin/supervisord", "-c", "/etc/supervisor/conf.d/supervisord.conf"]

Launch command: docker run --rm -p 8989:8989 vnijs/rsm-editors

To view jupyter lab go to http://localhost:8989 and log in using "jupyter" as the password

This builds on another image:

I'm having this same error. I'm not sure whether I'm correctly installing the extension. I'm using "the littlest jupyterhub" installed using these instructions BTW.

Within the Jupyter terminal I ran this to attempt to install the relevant extensions:

pip install --user jupyter-server-proxy jupyter-theia-proxy

I installed Theia according to these instructions within the jupyter user's home directory (I tried installing in opt/theia but kept getting Error: ENOENT: no such file or directory, open '/home/jupyter-user2/p ackage.json' errors when I tried to run it from other directories). At this point I can run node_modules/.bin/theia start from the jupyter terminal in my jupyter user's home directory and Theia is accessible at /user/{username}/proxy/3000/#.

But if I try to launch Theia here I get a 500 that doesn't show up in the journalctl logs. The browser inspector shows same error as OP.

These are the last couple lines of the output of running sudo journalctl -u jupyterhub on the server. Nothing regarding the 500 ...

Your help is much appreciated (cc @yuvipanda)

Do I need to run some variant of jupyter nbextension enable ...? Everything I try generates something like the error below:

$ jupyter nbextension enable --py jupyter_theia_proxy

It's not clean, but Theia works in my docker container now FROM jupyter/datascience-notebook:6c3390a9292e RUN conda install nbserverproxy python-language-server flake8 autopep8 && \ jupyter serverextension enable --py --sys-prefix nbserverproxy && \ jupyter labextension install jupyterlab-server-proxy USER root RUN sudo apt update RUN sudo apt install -y ssh RUN sudo apt install -y curl RUN sudo apt remove nodejs RUN curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash - && sudo apt-get install -y nodejs RUN curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add - && \ echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list && \ sudo apt update && sudo apt install yarn USER jovyan RUN mkdir .theia && mkdir .theia/plugins .theia/extensions RUN pip install jupyter-theia-proxy COPY package.json $HOME WORKDIR $HOME RUN yarn RUN export NODE_OPTIONS="–max-old-space-size=4096" RUN yarn theia build RUN yarn theia download:plugins RUN export PATH="$HOME/node_modules/.bin/theia:${PATH}" USER root RUN ln -s /home/jovyan/node_modules/.bin/theia /usr/bin/theia USER jovyan RUN cp -r $HOME/plugins/* $HOME/.theia/plugins/

I have now Theia working with the latest versions of jupyter dockerstacks images. It's also working with JupyterHub on K8s when mounting the volume to the /home/jovyan folder. In your config.yaml, you need to copy back the files to the volumes, this code goes in the singleuser section :

lifecycleHooks: postStart: exec: command: ["/bin/sh", "-c", "test -f /home/jovyan/.copied || cp -Rf /usr/local/homecopy/jovyan/. /home/jovyan/; touch /home/jovyan/.copied"]

For the Dockerfile, they are some shortcuts that I took, mostly the symbolic link, if someone have a better approach. I installed Theai in an hidden folder and then made other symbolic links, it's because I want the root directory of the users in JupyterHub to be as clean as possible and that's the best way I found yet (we have only one directory appearing src-gen and the package.json file).
