Different number of components on the left hand side (1) than on the right hand side (2)

hey i am having trouble with remix
this is the error i got

TypeError: Different number of components on the left hand side (1) than on the right hand side (2).
--> contracts/FundMe.sol:45:9:
|
45 | (bool callSuccess ) = payable(msg.sender).call{
| ^ (Relevant source part starts here and spans across multiple lines).

---

And this is the function which contain the error

   function withdraw() public onlyAdmin {
    for (uint256 i = 0; i < funders.length; i++) {
        address funder = funders[i];
        addressToAmount[funder] = 0;
    }
    funders = new address[](0);
    // transfer

    (bool callSuccess ) = payable(msg.sender).call{
        value: address(this).balance
    }("");
    require(callSuccess, "the withdraw failed");
}

@hamzaelothmani , You are facing this issue because payable(msg.sender).call{value: address(this).balance}("") doesn't give only a boolean datatype , its just that we only need the boolean datatype , so what we can do is we can let the compiler know that we know other variable also exists by adding , after the callSuccess , So the line will be like :

(bool callSuccess,)=payable(msg.sender).call{value: address(this).balance}("");

Hope this solves you issue mate :)
