ValueError: No such metric AnnoyIndex when running neofuzz

[sambaPython24]

I get the following error:

/usr/local/lib/python3.12/dist-packages/neofuzz/process.py in index(self, options)
     75         vectors = self.vectorizer.transform(self.options)
     76         n_dimensions = vectors.shape[1]
---> 77         self.nearest_neighbours = AnnoyIndex(n_dimensions, self.metric)
     78         for i_option, vector in enumerate(vectors):
     79             self.nearest_neighbours.add_item(i_option, vector)

ValueError: No such metric

import annoy works in general, so it is installed.
