Got "missing r" error when using EAS + Metamask + etherjs

[xiaohou77]

Issue detail

In our dApp https://app.fairsharing.xyz/, when we make an onchain attestaion call, metamask returned the error as below snapshot,

We use EAS + Metamask + etherjs. When we change wallet app to like OKX, it works well.

Who should fix this issue and how?

I found a relative issue ethers-io/ethers.js#3926, seems we have to wait for etherjs to fix?
Or metamask should get this fixed?

Or we have to replace etherjs?

Please help look into this issue, it is blocking many users using our dApp now.

We have met a similat issue recently. This seems related to recent metamask upgrade.

We have same issues, upgraded to ethers 6.9.0 it seemed to have fixed it, but after a few days I encountered same issue again so it's not consistent. Whats the solution? Whats causing this? Thanks.

It seems to be caused by Metamask or WalletConnect's latest upgrades. They are working on a fix, so hopefully it will be resolved soon.

Any updated on this?

Any updated on this?

No, unfortunately. Does this still reproduce with the latest MetaMask?

I also encounter the same issue while deploying a contract with "ethers": "^6.8.1" and metamask extension at this date.

Uncaught (in promise) TypeError: missing r ...

Which contract?

[DloomPlz]

A custom factory contract, which is not related to eas at all

also have the same issue using "ethers": "6.7.0", "hardhat": "2.22.4" and MetaMask 11.15.6
but anyway transaction is success even with this error on local hardhat node

Updated: find out solution for me is to use
import { ethers } from "https://cdnjs.cloudflare.com/ajax/libs/ethers/6.13.0/ethers.min.js";
for my web app

@xiaohou77 So try to use "ethers": "6.13.0"

@itev4n7 please make sure to post it on Metamask's and ether's repos as well. This issue is unrelated to EAS.

I have submitted a issue on MetaMask repo: MetaMask/metamask-extension#25032
