script – Sending Bitcoin: Anticipated property “signature” of sort Buffer, acquired Uint8Array

I’m attempting to ship the bitcoin with my non-public key utilizing the script and the bitcoinjs-lib. I’m continually getting the error Anticipated property "signature" of sort Buffer, acquired Uint8Array over the road once I name pstb.signInput().

I’m not ready to determine how you can resolve this,

const ecc = require('tiny-secp256k1');
