TX Help - Unable to send transaction errors

This could maybe help: https://developers.cardano.org/docs/native-tokens/minting#sending-token-to-a-wallet
(Although it uses build-raw, while build is much easier.)

I have described it for another user, here: https://forum.cardano.org/t/transaction-submit-error-fails-to-send/106340/13?u=heptasean
