Metamask-extension: eth_signTypedData not sending result to browser

[1blockologist]

www.pareto.network not accessible with Metamask with today's version

The console log mentions that "This experimental version of eth_signTypedData will be deprecated", is there a new function we should be using, or is it the same method name with different logic inside? Since this message is still there and not actually deprecated yet, then this is a bug that needs a hot fix

anything I can help with?

I feel like a unit test would have noticed this

I am also having this issue. For me, just before the MM UI updates to reflect a spinner that never resolves, the message "cannot read property EIP712Domain of undefined" shows on the UI.

I found the same message in a failed test of eth-sig-util:
https://circleci.com/gh/MetaMask/eth-sig-util/48#config/containers/0
https://github.com/MetaMask/eth-sig-util/pull/20
which was resolved by using the renamed method, signTypedDataLegacy

Perhaps the extension is calling signTypedData? Still looking into this will update if I find anything else of interest.
