RSA_padding_check_PKCS1_type_2:pkcs decoding error

I need to decrypt a message with the following logic

Logic RSA/ECB/PKCS1Decryption(Base64Decode(encryptedKey),B2C.cer)

Tried with two modules crypto & node-RSA returns a similar error.

RSA_padding_check_PKCS1_type_2:pkcs decoding error

Code

const privateKeyForDecryption = fs.readFileSync(path.resolve("./nsBank.key"));

// node-rsa module

function RSA_Decrypt(str){
    var key = new nodeRSA(privateKeyForDecryption);

    key.setOptions({encryptionScheme:'pkcs1'});

    const decrypted = key.decrypt(str, 'base64');

    return decrypted;
}

Error enter image description here // crypto module

function RSA_Decrypt(str){
    const buffer = Buffer.from(str,"base64");
    const decrypted = crypto.privateDecrypt({key:privateKeyForDecryption,padding:crypto.constants.RSA_PKCS1_PADDING}, buffer);
    return decrypted;
}
