I could not send through amethyst but I was able to send directly to his lnurl from the wallet app. I think this bug specifically applies only when 2 wallet of satoshi addresses try to zap each other in amethyst. From what I have gathered it seems any other wallet can zap through amethyst to a wallet of satoshi just fine. But only when a wallet of satoshi address tries to zap another one through amethyst this error happens.
