Truffle: VM Exception while invoking the SC-defined Ether transfer function

Question

I have two Smart contracts SC1 and SC2, I am sending ether from SC1 to SC2.

pragma solidity 0.5.16;
contract SC1 {
    address owner;
    constructor() public {
        owner = msg.sender;
    }
    function transferTo(uint amount, address payable dest ) public {
        require(tx.origin == owner);
        dest.transfer(amount);
    }
    function () external payable{
    }
}

==

pragma solidity ^0.5.16;
interface SC1 {  
   function transferTo(uint amount, address payable to   ) external;
}
contract SC2{

    uint public  count;
    address owner;
    constructor() public {
        owner = msg.sender;
    }
    function() external payable  { 
      count++; 
      if (count < 2 ) 
         TxUserWallet(msg.sender).transferTo(msg.sender.balance, address(this));
      
   }
}

truffle script

var assert = require('assert');
const path = require("path");
const fs = require("fs");


module.exports = async function(callback) {
  try {
     let arg1 = ""
     let arg2  = ""
     let  amount = '6'
     const accounts = await web3.eth.getAccounts();
     const acc2 = accounts[2];
     transferFuncName= "transferTo"
     const vic= artifacts.require("SC1");
     const att= artifacts.require("SC2");
     const vicobj = await vic.new();
     const attobj = await att.new();
     result1 = await web3.eth.sendTransaction({to:vicobj.address, from:acc2, value: web3.utils.toWei(‘11’)})
    
     arg2 =  attobj.address
     arg1 = web3.utils.toWei(amount,"ether")
     result2 = await vicobj[transferFuncName](arg1, arg2, {from:accounts[0]})
    }
 catch(error) {
    console.log(error)
  }

  callback()
}

I am getting following error message:

Somebody, please guide me.

I found the solution for this problem: SC2 should be like this:

pragma solidity ^0.5.16;
interface SC1 {  
   function transferTo(uint amount, address payable to   ) external;
}
contract SC2{

    uint public  count;
    address owner;
    constructor() public {
        owner = msg.sender;
    }
    function() external payable  { 
     
      
   }
}
