I am trying to sign data with psbt but getting the error below:

Error: Can not sign for input #1 with the key

Here is my sign data code:

 export function SignData(unsignedData: any, privateKey: string) {
 console.log('Signing data...');

 const psbt = bitcoin.Psbt.fromBase64(unsignedData.psbtBase64);

 const keyPair: ECPairInterface = ECPair.fromWIF(privateKey)

 psbt.signInput(1, keyPair)

 const signedBuyingPSBTBase64 = psbt.toBase64();
 return signedBuyingPSBTBase64;
}

sample unsignedData:
