Reverted with reason string 'Governor: unknown proposal id

Support Contracts
1

I using Governor contract from Openzeppelin. I have created and voted on the proposal. The state of proposal is succeeded. When I am trying to queue the proposal I am getting error

Reverted with reason string 'Governor: unknown proposal id

Here’s the queue data:

    const box = await ethers.getContract("Box");
    const encodedFunctionCall = box.interface.encodeFunctionData(STORE_FUNCTION, args);
    const descriptionHash = ethers.hashMessage(PROPOSAL_DESCRIPTION);

    const governance = await ethers.getContract("GovernorContract");
    console.log("Queueing...");
    const queueTx = await governance.getFunction("queue")(
        [await box.getAddress()],
        [0],
        [encodedFunctionCall],
        descriptionHash
    ); ```

The constants are correct. I think there could be something wrong with the hashMessage for description but not sure.

Please share a link to your contract (etherscan, github, etc).

Governor Contract:

Here’s the link to GitHub:

Note some of the ethersv6 methods haven’t been pushed to GitHub.

Please share these values as well.

export const STORE_FUNCTION = "store";
export const NEW_STORE_VALUE = 77;
export const PROPOSAL_DESCRIPTION = "This proposal shall execute the box store function to save the uint256 passed through proposal";

Please share the address of this contract, and if it's not verified, then also the relevant source code (of function store).

I have updated the codebase on github:

I am also getting the error-message unknown proposal id (using web3.js instead of ethers.js).

When replacing the call to function queue with a call to function hashProposal, I get the proposal ID:

I have fetched all ProposalCreated events emitted on your contract, then printed their proposal IDs:

None of these IDs corresponds with the one that you are trying to process, hence the error-message.

Ok! Is it the problem with hashMessage ethers' method. Yes it worked after changing const descriptionHash = ethers.hashMessage((PROPOSAL_DESCRIPTION)); to const descriptionHash = ethers.id((PROPOSAL_DESCRIPTION));

Could be any of the parameters that you pass to function queue (or to function hashProposal).

I have printed all the rest of the relevant information in those events:

description: This proposal shall execute the box store function to save the uint256 passed through proposal

As you can see, there are actually two proposals baring this description, so it is not the problem.

However, you may notice that one of them has used:

values = [ '2409' ]`

And the other one has used:

values = [ '1992' ]`

When I try 2409, I get the error-message proposal not successful.
And when I try 1992, the function call completes successfully.
Trying it again, I get the error-message proposal not successful.
Probably due to this transaction, which has just been executed.
