Function "is not a function" in Truffle dev

Question

I am not sure why I am being told my function is not a function.

I am doing calls as I always do from the Truffle console.

pragma solidity >=0.4.22 <0.6.0;

contract store {
    string public storage_;

    function store_it(string memory s) public {
        storage_=s;
    }
}

stor = store.at(store.address)

stor.store_it("string")

TypeError: stor.store_it is not a function

What is going wrong?

Answer 1

It seems you are using truffle v5. In that version you have to use await to obtain the result of .at

stor = await store.at(store.address)
stor.store_it("string")

Answer 2

In truffle version 5.0, you have to use await to obtain the result of contract.

let contract = await ContractName.deployed()
let result = await contract.functionName()
