Error: invalid object key - from

pragma solidity ^0.6.3;

contract SimpleStorage {
  string value;

  event ValueChanged(address indexed author, string oldValue, string newValue);

  constructor(string memory _value) public {
    setValue(_value);
  }

  function getValue() view public returns (string memory) {
    return value;
  }

  function setValue(string memory _value) public {
    emit ValueChanged(msg.sender, value, _value);
    value = _value;
  }
}

Deploying the contract

const provider = new ethers.providers.Web3Provider(
  ganache.provider()
);
const SimpleStorageContractFactory = new ethers.ContractFactory(
  simpleStorageJSON.abi,
  simpleStorageJSON.evm.bytecode.object,
  provider.getSigner(accounts[0])
);
simpleStorageInstance = await SimpleStorageContractFactory.deploy(
  'hello world'
);

Then the below line throws

const receipt = await simpleStorageInstance.functions.setValue('hi');

The line throws on ethers v5, while it works for ethers v4.

To reproduce with the files:

$ npx create-solidity-project testproject
$ cd testproject
$ npm test

The above line will prepare you a quick simple project with ethers v5 (that does the above) to reproduce the error.

@ricmoo This might be related to #321. Looks like the contract along with JsonRpcProvider is injecting a from, and the checkProperties is not happy with the from. Can you please have a look?

@zemse No worries. You never need to reply. I just worry sometimes about closing an issue too early on people. If something seems resolved I’ll close it eventually. Right now I’m going through a little more aggressively than usual, because I’m planning tome v5 out of beta in a week, and am trying to clear out the issues a bit so I can make sure I haven’t missed any features or issues people have had.

Glad you’re safe, and make sure you stay safe. That’s more important than adding “issue resolved” metadata to an issue. 😉

Thanks for the explanation, it cleared the doubts I had.

And I’m sorry if you thought I didn’t reply quickly. Actually, 2 days ago we had a cyclone here and electricity was out due to damage and it just got fixed. My last message happened to be the last one I did during the calamity just before the power outage. Now it’s alright here but TBH all this time offline I was eagerly waiting for coming online again to check the reply. And I’m thankful for the time you give to come up with quick fixes.
