Priyank Gupta Thanks. Amazing tutorial!

Very good tutorial. Couple of fixes to get it work today after some libraries updates^ Due to actual version of OpenZeppelin v5+ its necessary to use 0.8.20+ version of Solidity. 0.8.23 works OK as of now. Because of the same OppenZeppelin major version change it's necessary to add Ownable super class initialization: in file lib/solidity-examples/contracts/lzApp/LzApp.sol change constructor to constructor(address _endpoint) Ownable(_msgSender()) { lzEndpoint = ILayerZeroEndpoint(_endpoint); } In the scripts section you have to change MyScript name to DeployMumbai and DeploySepolia.
