PollingBlockTracker - encountered an error while attempting to update latest block

I'm not sure what causes this, but reading https://github.com/MetaMask/web3-provider-engine/issues/311 there seems to be a bug in web3-provider-engine. Updating to the latest version fixes the problem.

This happened in the sablier burner wallet, both in the home page and the withdrawal page. Here's the source code: https://github.com/sablierhq/sablier/tree/develop/packages/burner-wallet

For anyone who lands on this issue in the future: it means you need to create a .env file with REACT_APP_INFURA_KEY defined in it. See documentation for more details.
