It seems like the originator envelope does not have a keypackage back from the server/its empty: https://github.com/xmtp/libxmtp/blob/main/xmtp_proto/src/convert.rs#L62
Maybe shouldn't be an error -- empty response of keypackages might not mean an error, just that the user hasn't uploaded a keypackage yet (edited)
