Error message is shown and can't view data:

Steps to reproduce:

1. Updated Data Wrangler to latest version
2. Open VSCode, run code below.
3. Try to view data from variable

import pandas as pd
import polars as pl
path_news_folder = '../datasets/stock_news_benzinga/'
news_partners = pl.read_parquet(path_news_folder+'raw_partner_headlines_with_similarity_threshold_80pc.parquet')
news_analysts = pl.read_parquet(path_news_folder+'analyst_ratings_processed_with_similarity_threshold_80pc.parquet')

news_partners = news_partners.rename(mapping={'Max Similarity':'Max Daily Similarity'})
news_analysts = news_analysts.rename(mapping={'Max Similarity':'Max Daily Similarity'})

news_analysts_pd = news_analysts.to_pandas()
news_partners_pd = news_partners.to_pandas()

Update: last version that works for me is 1.0.2. From 1.2.0 and above it does not work

Hi Vitor (@Vitorbnc), thank you for reporting this issue! I can reproduce this on my end as well using the same version of Data Wrangler and Jupyter that you have installed. This error is happening because the version of Jupyter you have (around 5 months old) is missing a property that we're looking for.

The good news is that you should be able to work around it without changing your Jupyter version by tweaking a setting. Could you please check if you have this setting enabled and if so, could you try unchecking it and trying again on 1.2.1?

Please let me know if this works. Thanks!
