Cannot call sdk.nft.mint. Fails with "ethereum.signTypedData is not a function"

[figs999]

I am using the following code, which is effectively the minimal test case for sdk.nft.mint and it is failing.
A support developer on Discord could not find the reason, so I am perplexed.

This is my code:

import { toAddress } from "@rarible/types"
import { createRaribleSdk } from "@rarible/protocol-ethereum-sdk";
const Web3 = require('web3');
	
export default async function mint (tokenID) {
	const { ethereum } = window;
	if (ethereum && ethereum.isMetaMask) {
		console.log('Ethereum successfully detected!')          
		// configure web3
		const web3 = new Web3(ethereum)
		// configure raribleSdk
		const sdk = createRaribleSdk(web3, 'ropsten');
		const [sender1Address] = [...]

		const _nftCollection = {
			features: ["SECONDARY_SALE_FEES", "MINT_AND_TRANSFER"],
			id: toAddress("..."),
			name: "...",
			type: "ERC721",
			version: "ERC721V3",
		}

		let mintReq = {
			collection: _nftCollection,    // Collection info
			uri: "",       // Token URI
			royalties: [{ account: sender1Address, value: "850" }],
			creators: [{ account: sender1Address, value: "10000" }],
			lazy: true,    // The token will be lazy minted or not,
			nftTokenId: tokenID
		}

		result = await sdk.nft.mint(mintReq) //  <------------------    Error is thrown here
		console.log (result)
	}
}

Does this code work for anyone else? Is sdk.nft.mint broken for everyone right now?

As far as I can tell, I am doing nothing more or less than the way that this method is called in all of the examples I can find on github and in documentation.

@figs999 what sdk version do you use?
Also, pls check latest protocol-example for code examples (or tests in protocol-ethereum-sdk repo)

I'm unable to reproduce now. I'm going to assume I had grabbed an unstable version of the SDK.
