buffer layout

[benjiqq]

instantiating coder

const coder = new RaydiumAmmCoder(idl as Idl);
const result = coder.instruction.decode(
    Buffer.from("0bf70a9c01000000006417427900000000", "hex")
);
console.log(result);

seems like issue with layout here

Same error.

Is there any solution for this issue or another way to decode the data from the program?
