The error is:

Warning: Unsafe lifecycle methods were found within a strict-mode tree:
    in StrictMode

componentWillMount: Please update the following components to use componentDidMount instead: Form(SimpleForm)

componentWillReceiveProps: Please update the following components to use static getDerivedStateFromProps instead: Field, Form(SimpleForm)

And the code that triggers this (I think) is:
https://github.com/erikras/redux-form/blob/7b75f1b71ace0bb4805f754347dbeb7ef96a812f/src/Form.js#L24-L26
