Variable declaration problem in truffle console

Question

I am trying to run a smart contract in truffle. In truffle console when I try to declare a variable, it says “undefined”. I have compiled and deployed the contract with no errors but don’t know what’s wrong. This is what I tried:

truffle(default)> var poe = ProofOfExistence1.deployed()

Answer 1

The reason it says “undefined” is because the variable is not declared and initiated properly. The reason for this is that when you use .deployed(), this returns a Promise and the command you are running ca not use Promise object. Instead, try the following command:

truffle(development)> ProofOfExistence1.deployed().then(function(a) { poe = a; })
