Severity: low

Description:
Invalid error in depositDSS() function

if we check this function in exchange.sol contract:

    function depositDSS(
        uint256 amount,
        address _tokenAddress
    ) external onlyOwner {
       require(IERC20(_tokenAddress).transferFrom(msg.sender, address(this), amount), "Token withdrawal failed");
    }

We can see it reverts with error of "Token withdrawal failed" while it should be:
"Token deposit failed"

Impact

Incorrect error can lead to confusion.

Recommendation

replace it with:
"Token deposit failed"
