web3.min.js:1 Uncaught (in promise) Error: invalid address

[dguhanus]

Hi Gregory,
Thank you for your wonderful explanation. I have successfully the migrated the contract into Ganache.
I am able to load the smart contract after "npm run dev". But when I enter any text into the textbox, it is throwing an error:
web3.min.js:1 Uncaught (in promise) Error: invalid address web3.min.js:1
at u (web3.min.js:1). Here are the screenshots

Try out this in your function "load" in the last line

   web3.eth.defaultAccount = App.account;

Will be like this

  load: async () => {
    await App.loadWeb3();
    await App.loadAccount();
    await App.loadContract();
    await App.render();
    web3.eth.defaultAccount = App.account;
  },

It worked for me
