document is not defined with react-on-rails

Current behavior:

The documentation says that server side rendering works with no configuration needed if you install @emotion/core in a React app. I am getting document is not defined during the SSR.

I am using @emotion/styled, not css or jsx, I’m not sure if that could be where my problem is?

import * as React from 'react';
import styled from '@emotion/styled';

const Container = styled.div(
  {
    marginTop: 6,
    position: 'relative'
  },
  props => props.css
);

The error looks to be coming from a createCache method.

To reproduce:

I can create an example app if needed but I don’t have one handy.

Expected behavior:

The page should render.

Environment information:

• react version: 16.8.0
• emotion version: 10.0.10

I am facing the same issue with ReactJS.net

Closing this because we have not received a repro case since September. It’s also definitely a problem with used tooling or its configuration - not something we can fix in Emotion.
