How to Call Smart Contract Function After Migrations

Question

In my 2_deploy_contracts.js file, I can successfully migrate all my contracts using the command truffle migrate. My problem is that after migration, I want to call a function from contract D and pass it the address of contract E.

My 2_deploy_contracts.js file looks like this (contract names replaced):

const A = artifacts.require("A");
const B = artifacts.require("B");
const C = artifacts.require("C");
const D = artifacts.require("D");
const E = artifacts.require("E");

module.exports = function(deployer) {
  deployer.deploy(A);
  deployer.deploy(B);
  deployer.deploy(C);
  deployer.deploy(D)
    .then(function() {
      return deployer.deploy(E, D.address);
    })
    .then(function() {
      return D.methods.setEContractAddress(E.address); // This line
    });
};

I have looked at other similar questions on this site but none have helped so far. How do I call the setEContractAddress() function from contract D after contract E is migrated?

Thank you for your help and time!

try this:

const D = artifacts.require("D");
const E = artifacts.require("E");

module.exports = async (deployer) => {
  await deployer.deploy(D)  
  const d = await D.deployed();    
  await deployer.deploy(E, d.address);
  const e = await E.deployed();
  await d.setEContractAddress(e.address);
};
