I am using sample-demo-wallet code.
When I try to perform withdraw operation I got the error,
"Expects a 32 byte hash value or hex encoded string. Got AAAAAAAAAGOla1xzqEpxiSodjmiO+g8="
in withdrawAsset.ts file,
.addMemo(new Memo(MemoHash, transaction.withdraw_memo))
withdraw_memo make the problem. I guess.
Looking for solutions
