Code Sample, a copy-pastable example

import pandas as pd
d = '{"columns":["col 1","col 2"], "index":["row 1","row 2"], "data":[["random s3://xyz/abc","wherever https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.read_json.html"],["c","d"]]}'
pd.read_json(d, orient='split')

Problem description

This leads to an error in pandas 1.1.x and works fine in <=1.0.5.

Expected Output

                     col 1                                              col 2
row 1  random s3://xyz/abc  wherever https://pandas.pydata.org/pandas-docs...
row 2                    c                                                  d
