ValidateTransferError: invalid memo keys

[Luchanso]

Tryed call validateTransfer(...) and got some error for valid transaction:

ValidateTransferError: invalid memo keys
    at validateMemo (D:\dev\ssr\node_modules\@solana\pay\src\validateTransfer.ts:97:40)
    at D:\dev\ssr\node_modules\@solana\pay\src\validateTransfer.ts:88:9

    at fulfilled (D:\dev\ssr\node_modules\@solana\pay\lib\cjs\validateTransfer.js:5:58)
    at processTicksAndRejections (node:internal/process/task_queues:95:5)

Simple playground: https://codesandbox.io/p/devbox/hardcore-mclaren-qtz7zg?file=%2Findex.js%3A28%2C7

function validateTransfer(...) not correct work when pass memo string, I think it's can be bug on: https://github.com/anza-xyz/solana-pay/blame/master/core/src/validateTransfer.ts#L97 because "instruction.keys" must contain single key about Signer

Hey 👋 I’m facing the same issue, did you manage to solve this ? Or the bug is still around ?
Thanks a lot !

I am also facing same issue... this is serious, I am trying to use memo to authenticate Solana Pay payments on server side.
I was going to use reference field but apparently many Solana mobile wallets don't even include the reference in the transfer transaction!

Workaround: create this file with commented this line in your local project, and use this function from it:
