Hi talents. It's urgent issues.
I'm trying to send maximum btc from a wallet. So I used send-crypt module to do it.
So it works on local side, but it doesn't work online. It shows erros like "Expected property "1" of type BigInteger, got n"
You can check attach file.
If you have ever experienced in it or can send maximum btc from a wallet using javascript, please reach out soon.
Thanks.
