The region.values.astype(str) returns a pandas StringArray which is not hashable and cannot be used with ParameterNodeAtInstant.__getitem__. Converting to np.array() ensures compatibility with the vectorial parameter lookup. Fixes TypeError: unhashable type: 'StringArray' when running microsimulations.

Summary
uprate_rentwhenregion.values.astype(str)returns a pandasStringArrayinstead of a numpy arrayParameterNodeAtInstant.__getitem__expects anumpy.ndarrayfor vectorial lookup, but pandas StringArray is not hashableProblem
When running microsimulations, the following error occurs:
This happens in
