Submit ballot hashcode mismatch

[cauetomaz]

I found the tool practical and functional! I just had one problem when trying to submit my basket, the signature in the metamask didn't arrive, then when I tried again there was a conflict in the submission hash code, so I just changed the allocated value of one of the projects and everything worked. Thank you for everyone's time and energy.

@carlbarrdahl perhaps we can help here?

I haven't been able to reproduce this @cauetomaz. What wallet did you connect and sign with?

I used a metamask wallet on my android.

This was potentially caused by the updated ballot wasn't used (slow network connection could cause an older instance of the ballot to be used)

We now fetch the latest ballot (using refetch) before creating the message and signing it.

	const { refetch } = useBallot();
	const { mutateAsync, isLoading } = api.ballot.publish.useMutation({
	onSuccess,
	});
	useBeforeUnload(isLoading, "You have unsaved changes, are you sure?");
	const { signTypedDataAsync } = useSignTypedData();
	return useMutation(async () => {
	if (chain) {
	const { data: ballot } = await refetch();
	const message = {
	total_votes: BigInt(sumBallot(ballot?.votes)),
	project_count: BigInt(ballot?.votes?.length ?? 0),
	hashed_votes: keccak256(Buffer.from(JSON.stringify(ballot?.votes))),

	const signature = await signTypedDataAsync({
	...ballotTypedData(chain?.id),
	message,
