How to get the value of an array containing a Struct?

[andreachello]

I have this contract

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.17;

contract Greeter {
    struct Proposal {
        string name;
        uint voteCount; 
    }
    Proposal[] public proposals;

    constructor() {
        proposals.push(Proposal("Proposal 1", 1));
    }
}

what is the interface used to call the proposals array?

async function callFunction(vm: VM, contractAddress: Address, caller: Address) {
  const sigHash = new Interface(['function proposals((string,uint256))']).getFunction('proposals')!.selector

  // Encode the parameter
  const encodedParams = new AbiCoder().encode(['uint256'], [0])

  // Combine sigHash with encoded parameters
  const data = hexToBytes(sigHash + encodedParams.slice(2))

  const greetResult = await vm.evm.runCall({
    to: contractAddress,
    caller,
    origin: caller, // The tx.origin is also the caller here
    data,
    block,
  })

  console.log("greetResult", greetResult);
  

  if (greetResult.execResult.exceptionError) {
    throw greetResult.execResult.exceptionError
  }

  const results = new AbiCoder().decode(['(string, uint256)[]'], greetResult.execResult.returnValue)

  return results[0]
}

Ok, if you resolved this, could you also post how you resolved this? If someone else would stumble upon this issue that would be helpful, thanks!

The interface input is a uint!
