Investigate: provider.waitForTransaction not working with TestRPC

I’m having problems with getting an address of deployed contract, is there something silly I’m doing here?

const ethers = require('ethers');
const TestRpc = require("ethereumjs-testrpc");

const wallet = ethers.Wallet.createRandom();

const port = 8546;

const testRpc = TestRpc.server({
  port,
  logger: console,
  blocktime: 0.5,
  network_id: 15,
  unlocked_accounts: [ wallet.address ],
  accounts: [{
    balance: '8000000000000000000000000000000000000000000000000000000000000000',
    secretKey: wallet.privateKey
  }]
});

// pragma solidity ^0.4.15;
//
// contract HelloWorld {
//   function helloWorld() public pure returns (string) {
//     return "hello world!";
//   }
// }

const bytecode = '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';

const abi = '[{"constant":true,"inputs":[],"name":"helloWorld","outputs":[{"name":"","type":"string"}],"payable":false,"stateMutability":"pure","type":"function"}]';


async function main() {

  // Start testRpc.

  // Set wallet's provider.

  console.log(waitResult);

One other note though, you can compute the contract address using:

// sendResult is the transaction object returned from wallet.sendTransaction
var contractAddress = ethers.utils.getContractAddress(sendResult);

This should be fixed now in ethers-providers 2.1.11. If you blow away package-lock.json and 'node_modules/and do annpm install` it should all be peachy now, in TestRPC.
