I deployed a contract through remix and then I run the following code

    .then(instance => {
    c = instance;
    return c.getCreator();
    .then(result => {
    .catch(error => {

It spits an error saying Error: HelloWorld has not been deployed to detected network (network/artifact mismatch)

HelloWorld is just a JSON file that contains my ABI/Binary/etc generated from truffle

  • Is the contract deployed to a local network i.e testrpc or to a different netwok ?

Make sure that:

  • the truffle web3 provider is connected to the same network which you deployed to.
  • the ABI file contains the deployed contract address.

You can also specify the contract address to use:

.then(instance => {
  // ...

If deploying make sure that:

  • What if I don't use MyContract.at(contractAddress) but instead MyContract.new() ? It spits an Error: Invalid address Dec 1, 2017 at 0:42
  • @JorahFriendzone that error is because it's not detecting a connected wallet. If you have one connected, then also include the {from: account} option Dec 1, 2017 at 1:44
