Solidity: Neither address.send nor address.transfer nor address.call is working

Question

Problem

Whenever I call the paytest function (please see code snippet below) from javascript (please see code snippet below) i receive the below posted error message. Whether i use address.send, address.transfer or address.call, doesnt matter.Nothing works. I have plenty of test ETH on all accounts.

I use hardhat for my local blockchain.

Please help me. i am getting insane.

Solidity Code

    contract DC is ERC1155, Ownable {
    
    function paytest (address receiver, uint256 amount) public payable{
            (bool success, bytes memory _data) = payable(receiver).call{value:amount}("");
             require (success, "transaction failed");
             data=_data;
    }

    event Log(string fun, address sender, uint value, bytes data);

    fallback() external payable {
        emit Log("fallback", msg.sender, msg.value, msg.data);
    }

    receive() external payable {
        emit Log("receive", msg.sender,msg.value, "");
        
    }

Javascript File

   async function main () { // boiletplate function 
    
    
    const address = '0xDc64a140Aa3E981100a9becA4E685f962f0cF6C9'; // actual contract address
    const DC = await ethers.getContractFactory('DC');
    const dc = await DC.attach(address);
    
    const [owner, addr1, addr2] = await ethers.getSigners(); 
    await dc.connect(addr1).paytest(address,ethers.utils.parseEther("1.0"));

Error message console

There is a small syntax error in your code. You cannot send the required ETH directly in the function like that. You have to send it in a different block under the name "value". So, instead of:

await dc.connect(addr1).paytest(address,ethers.utils.parseEther("1.0"));

Try this,

await dc.connect(addr1).paytest(address,{ value: ethers.utils.parseEther("1.0")});

Update: The other method I personally use to use convertWithDecimal() function when inputting the value of ETH. The function automatically handles the BigNumber errors.

const isInt = (n: any) => {
  return n % 1 === 0;
};

const convertWithDecimal = (value: any, decimal: any) => {
  if (value > 0) {
    if (isInt(value)) {
      value = parseInt(value);
      value = BigNumber(value).multiply(decimal);
    } else {
      value = value * decimal;
      value = toFixed(value);
      value = parseInt(value.toString().split(".")[0]);
      value = toFixed(value);
      value = BigNumber(value);
    }
    return value.toString();
  } else {
    return 0;
  }
};

const toFixed = (x: any) => {
  if (Math.abs(x) < 1.0) {
    var e = parseInt(x.toString().split("e-")[1]);
    if (e) {
      x *= Math.pow(10, e - 1);
      x = "0." + new Array(e).join("0") + x.toString().substring(2);
    }
  } else {
    var e = parseInt(x.toString().split("+")[1]);
    if (e > 20) {
      e -= 20;
      x /= Math.pow(10, e);
      x += new Array(e + 1).join("0");
    }
  }
  return x;
};

Just paste it in your JS file and when inputting ETH value, change the syntazx to this.

await dc.connect(addr1).paytest(address,{ value: convertWithDecimal(1, 10**18});
