It seems that this condition need to be adapted Replacing 

return metadata.entry_points.select(group=group, name=name)

by 

return metadata.entry_points().select(group=group, name=name)

solves the error.

In fact, the doc says entry_points() and not entry_points --> https://docs.python.org/3.10/library/importlib.metadata.html#entry-points
