Intellisense not working with jupyter extension

What happened?

With a new python environment, created a new notebook and interactive window with a single import statement (import os). Intellisense does not work on this import (either hover hint or go to def). This is true for both Jedi and Pylance language server. Pylance does give an error in the log:

2024-05-21 10:07:22.134 [info] a [Error]: Request workspace/configuration failed with message: Cannot read properties of undefined (reading 'metadata')

  data: undefined
}

Intellisense comes back in these windows if the jupyter extension is disabled. In some cases Pylance does work inconsistently, seemingly dependent on what is open when the window is reloaded (if only preferences are focused, I get no error and intellisense works, but not sure how consistent this is), but Jedi seems consistently blocked.

Jedi doesn't currently support notebook models, so that's not expected to provide intellisense since IW is backed by a notebook.

Are you executing the import statement in the interactive window? Pylance doesn't provide intellisense until the first cell is executed (known issue)

[tmchartrand]

@amunger yes the behavior is no different for me before or after execution of a cell (in either notebook or interactive window). When checking this though, I did realize that the effect of the jupyter extension enabled vs not is also inconsistent, modified the original post to reflect this. The presence of the error log noted does seem to be consistently linked to the bug as far as I can tell, although only on the pylance side not jedi.

I'm confused by your comment on Jedi though, since it is working just fine for me in an older version (code 1.85.2, python 2024.2.1, jupyter 2023.9.100. Are you referring to features that use the active kernel vs just static analysis (eg jupyter.enableExtendedKernelCompletions)?

As a side note, it would be great if the respective notebook support for pylance and jedi was better documented in general!

@DonJayamanne Cannot read properties of undefined (reading 'metadata') sounds like it may be trying to access metadata through the custom field, is there a setting/experiment to toggle to verify that?

[DonJayamanne]

@bschnurr @heejaechang Please can you have a look at this.
Last iteration we changed the way metadata is stored in the notebook, its no longer nested under metadata.metadata.

[tmchartrand]

After doing some coarse search of older versions, it seems like this issue was introduced with the 2023.11 version of the extension.

@tmchartrand Are you still running into this issue.

Happy Coding!

This is still an issue with extension versions jupyter v2024.6.0, python v2024.10.0. Please re-open!

[tmchartrand]

I've confirmed that the pylance side actually seems fine in the recent extension versions, but the issues with non-Pylance intellisense continue. Opened new issue to reflect that.
