Error 404 No such file or directory

Jupiter Lab 4.0.2

When I try to save and export the notebook as HTML or any other format I get a 404 error. Below is the output in from Anaconda Prompt.

[W 2023-08-04 11:47:19.166 ServerApp] 404 GET /nbconvert/HTML_NoInput/RTC%3ATest.ipynb?download=true (::1): No such file or directory: RTC:Test.ipynb
[W 2023-08-04 11:47:19.169 ServerApp] 404 GET /nbconvert/HTML_NoInput/RTC%3ATest.ipynb?download=true (0043a24c16a345a9a677f3d39b54e503@::1) 203.16ms referer=http://localhost:8888/lab/tree/RTC%3ATest.ipynb

In the above my notebook is called Test.ipynb

I have tried removing and reinstalling nbconvert but no luck. It seems to suggest that the notebook does not exist. I have tried on various notebooks stored in different file locations but I have the same issue. Any help anyone could offer would be greatly appreciated.

Looks like jupyterlab/jupyter-collaboration#151

Thanks for the response. This does look like the same issue. I will close this one.

Please reopen this issue. See also the recent discussion in jupyterlab/jupyter-collaboration#183. This seems to be very much an issue of nbconvert (as it can't deal with custom drives) and not jupyter-collaboration.

Thank you for linking the discussion above @f14h, I didn't know about the custom drive mechanism before. That said, I still think the issue lies not with nbconvert. Having read the discussion above, I believe a better place to fix this problem is the JupyterLab component that calls nbconvert (somewhere in here maybe?).

While it may be relatively easy to check if a given filename starts with RTC: and if so strip it, fixing it in JupyterLab seems more principled and robust for other custom drives (and also consistent with this comment).

This is of course only my opinion, I am happy to hear more from others. However, I am reluctant to reopen the issue now given my reasoning above, unless there is more interest/discussion (or someone else decides to do it).
