Hello, I’m a newcomer who followed the GitHub bot’s guidance. \-_-/ YAY
First of all, thank you for your interest in reading about the extension issue that i experienced.
i experienced jupyterhub+jupyterlab freeze when I tried to use it with the jupyter-collaboration extension suite. I could only access files just being in my home directory (not a subdirectory of it) before I met the freeze condition. I thought this was JupyterHub’s bug (but it really is not) 
i … solved this problem by removing jupyter-collaboration, jupyter-collaboration-ui,
and related material, such as remaining files and directories, manually. I cannot find, and I have a question about the essential cause of why that extension held JupyterHub to avoid work anymore. Of course, I explored this forum to see how many person experienced a similar problem. It looks like almost abandoned by users who have enough experience using JupyterHub.
…Yes, i wrote much small talk that is not important. My main question is … in the above title.
i would like to share and get some useful information to consider using jupyter-collaboration extension. If it works well, it will really useful for all.
…
If there is some way to make it work well, I would like to appreciate.
I did not see that before.
Are you using the latest versions?
If so, it would be super valuable if you could share more details and report it as a potential issue in the GitHub - jupyterlab/jupyter-collaboration: A Jupyter Server Extension Providing Support for Y Documents repo.
It looks like almost abandoned by users who have enough experience using JupyterHub.
What looks abandoned, extension or forum? Why does it look like that to you?

Yes, I am using JupyterHub 5.3.0 + JupyterLab 4.4.5,
I tried to attach jupyter-collaboration 4.1.0 + jupyter-collaboration-ui (2.1.0)
and I had run command as # jupyter lab build
I meant “Extension project looks like abandoned”.
I found some of question handling similar problem .
(and that was just closed by “reinstallation” comment)
remove and reinstallation is not essential solution i think.
Observing a log and find core problem is important and useful to clear problem permanently.
So … ok. your providing link would be helpful. I will reply after I find why I did not solve that problem (from the document, and try to solve it.). Thank you in advance.
Ok … i seem to make jupyter-collaboration working with jupyterlab,
This condition look like clean installation of jupyter-collaboration.
i found that python notebook cannot open if that is not in home folder root.
if my home folder root is /home/meow, /home/meow/jupyter_note.ipynb can be opened,
but /home/meow/jupyter/jupyter_note.ipynb is not.
this problem is also occurred in situation
if /data/workspace/jupyter is linked to /home/meow/jupyter
and I am about to open /home/meow/jupyter/jupyter_note.ipynb.
is there some way to turn on verbose (debug) log that can show how extension works?
i would like to see in detail not only about access to jupyterhub endpoint,
but also additional messages if there are some problem.
