For more information try --help

This error message points at a problem, because the nullifier isn't a Decaf377 point, it's an Fq element. Probably this is just an error message issue?

This is just an error message issue, because the FieldExt trait uses the EncodingError type from decaf377.

Closing since this is just an issue with the error message
