Failing to create proposal through Snapshot.js

[jamesdobry]

Hello,

I am trying to integrate Snapshot into my dApp and am struggling with a few things since the documentation is very sparse.

When I go to create a proposal, I have no idea what to set the snapshot variable to. Also, what is allowed to be dumped to the metadata variable?

The main issue right now is when I go to publish, I get the following error:

Error: overflow (fault="overflow", operation="BigNumber.from", value={LONG NUMBER}, code=NUMERIC_FAULT, version=bignumber/5.5.0)

Does anyone have any ideas? I am passed in the wallet address into the second parameter and I am not setting the from variable.

Thanks for the help,

James

I think I can answer for the first part, snapshot is the block number the closer to the creation of the proposal.
Not sure if metadata is mandatory.
@ChaituVR Maybe you can help ?

@jamesdobry Hello,

snapshot is the block number of the network, ideally, pass the latest block number while creating a proposal
metadata can be ignored
Not sure what is the error is about, is your code open-source?

This code sandbox https://codesandbox.io/s/vibrant-dawn-u7r43 might be helpful

Thank you! So the error that was being thrown was due to my start/end timestamp calculations were being off.

@jamesdobry @ChaituVR Greetings!

I am running through the same issue, in what format should end and start be?

const date = Date.now();
const blockNumber = await web3.eth.getBlockNumber();
const isValidProposal = snapshot.utils.validateSchema(
snapshot.schemas.proposal,
{
	space: "zerti.eth",
	type: "basic",
	choices: ["For", "Against", "Abstain"],
	title: `Should 0x00 be added to the Zerti DAO as an entity?`,
	body: "test",
	start: date,
	end: date + 432000000, 
	snapshot: blockNumber,
	network: "5",
}
	);
	console.log('Proposal', isValidProposal);

@LucasGrasso What error do you see? compare these values with the snapshot UI when you create a proposal on your space

import "./App.css";
import { Web3Provider } from "@ethersproject/providers";
import snapshot from "@snapshot-labs/snapshot.js";

function App() {
//const hub = "https://hub.snapshot.org"; // or https://testnet.snapshot.org for testnet

const hub = "https://testnet.snapshot.org";
const client = new snapshot.Client712(hub);

const Proposal = async () => {
const web3 = new Web3Provider(window.ethereum);
const [account] = await web3.listAccounts();

console.log({ account });

const blockNumber = await web3.getBlockNumber();
console.log({ blockNumber });

const receipt = await client.proposal(web3, account, {
  space: "yam.eth",
  type: "single-choice", // define the voting system
  title: "Test proposal using Snapshot.js",
  body: "This is the content of the proposal",
  choices: ["For", "Against", "Abstain"],
  start: 1679565857,
  end: 1637244000,
  snapshot: blockNumber,
  network: "5",
  plugins: JSON.stringify({}),
  app: "my-app", // provide the name of your project which is using this snapshot.js integration
});

console.log({ receipt });
