example data not being pulled into ams processing notebook

In the anisotropy_plot_AMS notebook, the lines:

dir_path = 'example_data/anisotropy_slump'
result, magic_file = ipmag.download_magic_from_id('19571', directory=dir_path)
ipmag.unpack_magic(magic_file, dir_path, print_progress=False)
contribution = cb.Contribution(dir_path)

give an error message of this:
