A new Notebook job from a Jupyterlab UI from a ipynb file gives 'FileNotFoundError' object has no attribute 'response'

This was working just earlier and I don’t know how to debug this anything further using the UI

One thing I am noticing is the UI is forcing a prefix of RTC:.ipnb on each input. It didn’t use to do this and I think this is the problem It is not in RTC

What do you mean by notebook job? Are you using some kind of a scheduler extension (there are many)?

I’ve encountered the same issue. In my case, I was using the jupyter-scheduler extension in addition to the jupyter_collaboration extension.

I think this issue is because when opening a notebook file with the jupyter_collaboration extension enabled, the path is set to RTC:<filename>. For example, in the browser the URL would be <server>/lab/tree/RTC%3Ahello_world.ipynb. When clicking the “Create a notebook job” button from the notebook, then the RTC: prefix is still present in the Input file field in the Notebook Jobs UI.

However I did find a work-around for this. Modify the URL in the browser to exclude the RTC%3A bit, then reload the page. Then, after clicking the “Create a notebook job” button, the form is populated with the correct path.
