Data Wrangler (often) doesn't get called when trying to open a DataFrame from other frames on the call stack

[danhje]

This bug was originally reported over at the DataWrangler repo (link), but they think the issue lies with the Jupyter extension.

Environment data

• VS Code version: 1.92.2
• Data Wrangler Extension version (available under the Extensions sidebar): v1.8.0
• Jupyter Extension version (available under the Extensions sidebar): v2024.7.0
• Python Extension version (available under the Extensions sidebar): v2024.14.0
• OS (Windows | Mac | Linux distro) and version: Windows 11 with Ubuntu on WSL2
• Pandas version: 2.2.2
• Python and/or Anaconda version: 3.12
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): poetry venv

Expected behaviour

DataFrame opens in data view / Data Wrangler.

Actual behaviour

Nothing happens.

Steps to reproduce:

Put a breakpoint on the first return line of the following script, and run it in VS Code debugger.

import pandas as pd

def inner():
    inner_var = pd.DataFrame()
    return

def outer():
    outer_var = pd.DataFrame()
    inner()

outer()

The (empty) DF inner_var can be opened in DW. Now find the "CALL STACK" panel and click "outer". The "VARIABLES" panel now previews outer_var. But opening it in DW often fails, though not always.
