4.4.8 throws PropTypes validation warnings for React 14

For every component we use ‘connect’ in, we get the following JS warning on every render:

Warning: Failed Context Types: Calling PropTypes validators directly is not supported by the `prop-types` package. Use `PropTypes.checkPropTypes()` to call them. Read more at http://fb.me/use-check-prop-types Check the render method of `[NAME OF COMPONENT]`

Right now, each page load brings about 2000 of these warnings.

For example, using the following component throws warnings:

import React, { Component } from 'react'
import { connect } from 'react-redux'

class FeedCard extends Component {
  render() {
   return <div />
  }
}

export default connect(null, {
  updateFeedItem,
})(FeedCard)

But simply removing the ‘connect’ usage “fixes” the problem (although it renders the component useless):

import React, { Component } from 'react'
import { connect } from 'react-redux'

class FeedCard extends Component {
  render() {
   return <div />
  }
}

export default FeedCard

I confirmed that downgrading to 4.4.7 makes the issue go away. We are using React 0.14.8

Okay, react@0.14.9 and react-dom@0.14.9 are out, and they should play nice with prop-types. Other React-related packages were not updated. Let me know if it helps.

Look at Dan go!

Looks like the issue is upstream with React itself, so I’m closing this one out.
