Bug: Unable to use signTypedData_v4 in snapshot.org

[midgerate]

Describe the bug

In the compiled version of snapshot, I see an error but it works fine when running locally in dev

Steps

FYI - This might be snapshot.org specific problem, however it affects a large number of users of snapshot.org

1. Go to this URL https://snapshot-ztk9cr4q9-snapshot.vercel.app/#/pistachiodao.eth/proposal/0x08c3bd2960700525770a1d634f8599ba967e55fcc05b6c1649d984d88253769d
2. Connect with Coinbase wallet and try to vote
3. You will see an error in console

This only happens on build version and does not happen on development mode.

Here's how we create the provider (its inside @snapshot-labs/lock package)

Here's how we get the signer (its inside @snapshot-labs/snapshot.js package)

Expected behavior

It should open the confirmation in the mobile phone app.

Version

3.0.11

Additional info

FYI - I haven't tested this with the coinbase wallet chrome extension.

Desktop

• Browser - Chrome

Smartphone

• OS Android

Coinbase Wallet supports both eth_signTypedData_v3 and eth_signTypedData_v4.

Can you please clarify -

1. Are you testing using the Coinbase Wallet mobile app, or the browser extension?
2. What version(s) are you using for testing?

[samuveth]

@taycaldwell The issue occurs when you connect with the mobile app to a desktop running snapshot in chrome via QR code scan.

My app version is 28.2.17
