New ENS fails with Cannot read property 'sendPayload' of undefined

[novakov-alexey-zz]

I am trying to run a sample code to create ENS instance in my console and then to resolve some name. But it fails just on ENS creation.

Versions:

• Truffle v5.0.9 (core: 5.0.9)
• Node v11.12.0
• web3.version '1.0.0-beta.37'

I am using Geth with Rinkeby network.

truffle(rinkeby)> var ENS = require('ethereum-ens');
undefined
truffle(rinkeby)> var Web3 = require('web3');
undefined
truffle(rinkeby)> var provider = new Web3.providers.HttpProvider();
undefined
truffle(rinkeby)> var ens = new ENS(provider);
Thrown:
/Users/aa/dev/git/blockchain/isaqb-eth-solidity/node_modules/web3-providers/dist/web3-providers.cjs.js:49
      if (provider.sendPayload && provider.subscribe) {
                   ^

TypeError: Cannot read property 'sendPayload' of undefined

Hi, can you upgrade to the latest ethereum-ens (ver 0.7.6) and try again?

[novakov-alexey-zz]

Hi @makoto, this issue seems to be gone with latest version, but I have another problem:

var ENS = require('ethereum-ens');
    var Web3 = require('web3');

    var provider = new Web3.providers.HttpProvider("http://localhost:8545");
    var ens = new ENS(provider);

    ens.resolver('alexeyn.test').addr().then(function(addr) { console.log(addr) });

Thrown:
evalmachine.<anonymous>:0
ens.resolver('alexeyn.test').addr().then(function(addr) { console.log(addr) });
                             ^

TypeError: ens.resolver(...).addr is not a function

Is it something known?
So far I can't reach any success with ens js library, always some miss match :-(

@novakov-alexey sorry for taking ages to respond. Can you try with 0.7.7?

I think what was happening was it was picking up whatever the web3 version you have locally and ENS is not compatible with the later version of Web3.

So my fix is to fix web3 version to the known working version.

https://github.com/ensdomains/ensjs/compare/fix-web3js-version?expand=1

I created the following truffle script and run on the project where later version of web3 (1.0.0-beta.52) is installed and looks working fine.

ENS = require('makoto-ethereum-ens');
name = 'alexeyn.test'
module.exports = async function(callback) {
// Connect to infura using HDWalletProvider
// https://medium.com/coinmonks/deploy-your-smart-contract-directly-from-truffle-with-infura-ba1e1f1d40c2   
    let provider = web3.currentProvider
    let ens = new ENS(provider)
    console.log('owner', await ens.owner(name))
    console.log('address', await ens.resolver(name).addr())
    callback()
}

Hi @makoto, sorry for even longer delay in response. I have tried my script with new ENS version. However, it still fails somewhere between Node and my local Geth client:

Perhaps, I need to update Geth or so.

This looks like the same issue with web3 issuing broken RPC requests.
