Two identical functions inside a truffle migration

[Flowiotit]

The contract VestingWallet.sol from OpenZeppelin have two functions with the same name "vestedAmount", but different parameters to call a particular function.

The first one:

   function vestedAmount(uint64 timestamp) public view virtual returns (uint256) {
       return _vestingSchedule(address(this).balance + released(), timestamp);
   }  

Second:

   function vestedAmount(address token, uint64 timestamp) public view virtual returns (uint256) {
       return _vestingSchedule(IERC20(token).balanceOf(address(this)) + released(token), timestamp);
   }

I'm writing a truffle migration file to see how tokens vests after one month, for example.

const timestamp_Start = Math.floor(Date.now() / 1000);
const oneMonthLaterTimestamp = timestamp_Start + 30 * 24 * 60 * 60;
console.log("Vested amount after 1 month:", await myToken.vestedAmount(myToken.address, oneMonthLaterTimestamp));

It always ends with a failure:

Error: value out-of-bounds (argument="timestamp", value="0x00000000000000000000000018E1Def9870DFbDB0CF4E94440104E39393B53A2", code=INVALID_ARGUMENT, version=abi/5.6.4) 

And so on. I'm assuming that truffle calls the first one vestedAmount function and not seeing the second with different parameters, because if I locally change the name of the function to different - it gives the correct output. How do I implement this right if I want to call the second without changing the name of the function or without commenting selection of the first one function?

Need to refer to the overloaded function, by its key in contract.methods. In my case:

console.log("Vested amount after 1 month:", BigInt(await VestingWallet.methods['vestedAmount(address,uint64)'](myToken.address, oneMonthLaterTimestamp)));
