Truffle migrate Error: PollingBlockTracker

Question

I'm trying to deploy a contract on Avalanche Fuji testnet using Truffle. Here is my truffle config:

require('dotenv').config();
const mnemonic = process.env["MNEMONIC"];
const infuraUrl = process.env["INFURA_URL"]; //https://avalanche-fuji.infura.io/v3/...
 
const HDWalletProvider = require('@truffle/hdwallet-provider');

module.exports = {

  networks: {
    development: {
      host: "127.0.0.1",
      port: 8545,
      network_id: "*"
    },
    fuji: {
      provider: () => new HDWalletProvider(mnemonic, infuraUrl),
      network_id: "43113",
      gas: 5000000,
      networkCheckTimeout: 1000000,    
      timeoutBlocks: 200,
    }
  },
  ...
  compilers: {
    solc: {
      version: "0.8.13",      // Fetch exact version from solc-bin
    }
  }
};

When I run truffle migrate --network fuji, I get the following error:

}

Does anyone know what the issue is? Is it the Infuria API?

Answer 1

run npx truffle migrate --network goerli instead of truffle migrate --network goerli.
This Worked for me.
