I am using truffle: "^4.1.14" and ganache-cli version "^6.1.8". When I try to migrate to ganache cli network, it works without a problem. But when I try to migrate to Rinkeby, it always fails. The error message says TypeError: Cannot read property 'bind' of undefined. The problematic line is buried somewhere deep in webpack, and I can't get to that script to inspect it or console.log it.

The relevant part of truffle.js looks like this

rinkeby_infura: {
      provider: function() {        
        // using process.env.MNENOMIC would be safer, but this is test project
        const mnemonic = require('./.mnemonic');
        const apiKey = require('./.infura_api_key');
        return new HdWalletProvider(mnemonic, 'https://rinkeby.infura.io/' + apiKey);
      },
      network_id: 4,      
      gas: 4612388 // Gas limit used for deploys
    },

The full stack trace of the exception is below. It probably has something to do with connecting to Rinkeby via provider, at least from what I've googled so far. But I am unable to make it work.

$ ./node_modules/.bin/truffle migrate --network rinkeby_infura

  • The error message states in provider.sendAsync.bind that you are trying to read bind of undefined, so it is sendAsync is undefined. I remember that web3 0.20 -> 1.0 changed from provider.sendAsync() to provider.send() so perhaps there are some dependencies in your project that are using the wrong version of web3. – Ismael Feb 20 at 21:40

In my opinion Truffle is having trouble opening your mnemonic / Infura API key files. Is it working if you use directly the mnemonic and the API key instead of the variables?

Also I recommend you to use dotenv and process.env (even with a test project), it would be easier to handle future updates!

  • I know that using it in ENV variables would be safer, but this is just a test project, and this was easier set up. I've tried to include API key and mnemonic directly, but it did not change anything – David Votrubec Nov 14 '18 at 12:27
