Provider.on listener doesn´t work

Bugs

Hello,

It doesn´t enter in listening looping through the blocks when I execute the following code:

const { ethers } = require('ethers');
const infuraProvider = new ethers.providers.InfuraProvider('homestead', process.env.INFURA_API_KEY);

infuraProvider.on('block', async (blockNumber) => {

            console.log("blockNumber ", blockNumber);

        });

Here´s the output of console.log("infuraProvider ", infuraProvider);

infuraProvider InfuraProvider {

  • _isProvider: true,*
  • _events: [],*
  • _emitted: { block: -2 },*
  • disableCcipRead: false,*
  • formatter: Formatter {*
  • formats: {*
  •  transaction: [Object],*

  •  transactionRequest: [Object],*

  •  receiptLog: [Object],*

  •  block: [Object],*

  •  blockWithTransactions: [Object],*

  •  filter: [Object],*

  • }*
  • },*

  • projectId: ‘6021b8788d0648c285535dc157a95e6f’,*

    }

Would appreciate your help on this one.

Hi Sam,
I saw your case on ConsenSys support and replied with the below. If someone else has any other ideas please chime in!

This appears to work for me:

$ cat 945979.js
const { ethers } = require('ethers');
const infuraProvider = new ethers.providers.InfuraProvider('homestead', process.env.INFURA_API_KEY);

infuraProvider.on('block', async (blockNumber) => {

console.log("blockNumber ", blockNumber);

});
$ INFURA_API_KEY="..." node 945979.js 
blockNumber  15651935
blockNumber  15651936
blockNumber  15651937

Can you provide the error or other output you are getting?

Warm regards,
Chris | Infura | ConsenSys
