Transaction failure when trying to send ETH from a contract with the "call" function

[SmithJohnsonE]

Hello,

according to Lesson 4, one of the ways to send ETH from a contract is with call. As mentioned in the course, this has not a maximum gas cap like the transfer and send functions.

However, when I have the following, for a reason I get a failure.

(bool CallSuccess,)=payable(msg.sender).call{value: address(0x42E4E9bBb3cBAef2E40AD0750c7Ce5A89e4e3982).balance}("");
require(CallSuccess,"Call failed");

Your help would be priceless!!!

P.S. I am working on Sepolia network.

@SmithJohnsonE Could you please tell me about this?

address(0x42E4E9bBb3cBAef2E40AD0750c7Ce5A89e4e3982).balance

What is the balance of this address? and do you have that much balance in the contract to withdraw?

@SmithJohnsonE So does your contract has enough balance where your withdraw function is located?

Hmmm I am not sure if I understand correctly your question.

I have the contract "A", where the "withdraw" function exists. In this function, I try to transfer the balance of another contract "B" to the sender of the transaction (i.e., as sender of the transaction, I mean the address which initiated the "withdraw" function). In other terms I don't try to withdraw the funds of the contract A, but rather of the contract B.

The following screenshot shows the function "withdraw" in the contract "A".

At the time that the "withdraw" function is triggered, the balance of contract A is 0.066 ETH and of contract B is 0.011 ETH.

The error that I receive, while calling the "withdraw" function is this:

@SmithJohnsonE Can you please post the complete code? or a repository link?

Hello @SmithJohnsonE, the contract B has a function to withdraw ETH?
