Your contract has a constructor and expects an argument.

constructor(string memory initialMessage) public {
        message = initialMessage;
    }

So when you deploy it you have to pass an argument.

const Inbox = artifacts.require("Inbox");

module.exports = function (deployer) {
  // passing an argument 
  deployer.deploy(Inbox, "myInitialMessage");
};
