v4.9.0 breaks eth_signTypedData

[shaharsol]

my code that used to work:

web3.currentProvider.sendAsync({
      method: 'eth_signTypedData',
      params: [params, App.account],
      from: App.account,
    }, function (err, result) {
      callback(err,result)
    })

now I get this message in the console but nothing happens:

It's sporadic, but in some cases after I click the button that fires this function and then explicitly click the metamask fox on the toolbar, I get this window, which I'd expected to pop up:

yet, even after I sign, the callback is not called within my js code.

on another desktop, when i click "sign" i see an endless loading gif, and I managed to grab this from the "old ui" dev tools:

I bet the undefined EIP712Domain has something to do with the error?

Hi @shaharsol. This was caused by a premature version bump of a few of our dependencies and will be fixed by #4989. We plan to do a patch release shortly. Your existing dapp code should begin to work again at that time. Thanks for the issue report and for your patience!
