Line 283 in e252e54

ref_lens = (len(reference) for reference in references)

parameter ‘reference‘ is a type of list(list(str),dict(str)), but not list(str), so i think this line should be
'ref_lens = (len(reference[0]) for reference in references)'

The type of references is list(list(str)), like said in the docstring.
