Unable to Download ir.datasets.wu2020(): JSONDecodeError

[QWDxxx]

I am currently learning to use Scirpy for single-cell and immune repertoire analysis, but I encountered an issue with data downloading while trying to reproduce the tutorial.
When attempting to load the wu2020 dataset using the function ir.datasets.wu2020(), the dataset fails to download, and the following error is raised:
JSONDecodeError: Expecting value: line 1 column 1 (char 0)
Thank you in advance for your assistance, and I look forward to your guidance on resolving this issue!

import pooch
import pandas as pd
fname_bathymetry = pooch.retrieve(
    url="doi:10.6084/m9.figshare.22249894.v2",
    known_hash="md5:12c57c790f8a403751304c9de5a18cbf",
)

When I tried to download the dataset using the method provided on the Pooch official website, I encountered the following error:
ValueError: Invalid data repository 'doi.org'. To request or contribute support for this repository, please open an issue at https://github.com/fatiando/pooch/issues
Could this be due to a change in the URL? How can I download the currently available example dataset? Looking forward to your reply. Thank you!

I can't reproduce this and certainly nothing has changed on our end. Could this just be a temporary issue with doi.org or figshare? Or possibly you have very old version of pooch installed?

In any case, if nothing else works, you can download the files manually from figshare:
