Even after entering proper bytes32 value and address value. Setaddress function is not working

Question

I am getting generic error every time I try to modify the code. I am passing byte32 value as "0xabcd" and address value as "0xca35b7d915458ef540ade6068dfe2f44e8fa733c" in Setaddress function.

The error is as below:

"transact to EternalStorage.setAddress errored: VM error: revert. revert The transaction has been reverted to the initial state. Note: The constructor should be payable if you send value. Debug the transaction to get more information."

Below is my code

pragma solidity ^0.4.17;
contract EternalStorage {

address owner = msg.sender;
address latestVersion;

mapping(bytes32 => uint) uIntStorage;
mapping(bytes32 => address) addressStorage;

modifier onlyLatestVersion() {
   require(msg.sender == latestVersion);
    _;
}

function upgradeVersion(address _newVersion) public {
    require(msg.sender == owner);
    latestVersion = _newVersion;
}

// *** Getter Methods ***
function getUint(bytes32 _key) external view returns(uint) {
    return uIntStorage[_key];
}

function getAddress(bytes32 _key) external view returns(address) {
    return addressStorage[_key];
}

// *** Setter Methods ***
function setUint(bytes32 _key, uint _value) onlyLatestVersion external {
    uIntStorage[_key] = _value;
}

function setAddress(bytes32 _key, address _value) onlyLatestVersion external  payable{
    addressStorage[_key] = _value;
}

// *** Delete Methods ***
function deleteUint(bytes32 _key) onlyLatestVersion external {
    delete uIntStorage[_key];
}

function deleteAddress(bytes32 _key) onlyLatestVersion external {
    delete addressStorage[_key];
}
}

The error message says that the transaction to setAddress() reverted:

transact to EternalStorage.setAddress errored: VM error: revert.

There is only one requre() statement in setAddress(), in onlyLatestVersion():

require(msg.sender == latestVersion);

So it's virtually certain that the sender of the transaction (msg.sender) is not set to latestVersion. That means you either need to:

Make sure you are sending from the account that the contract has as the latestVersion, or...
Change latestVersion using the contract's function upgradeVersion(), so that it matches your transaction sender.
