TypeError: checker is not a function at validate

See original GitHub issue

somehow a weird warning is printed to the console when i have this property

  propTypes:
    links:       React.PropTypes.oneOfType(
      React.PropTypes.object
      React.PropTypes.arrayOf(React.PropTypes.object)
    )

the checkPropTypes() produces

error = TypeError: checker is not a function at validate

error = propTypes[propName](props, propName, componentName, location);

and this will print this warning in the console

Warning: Failed propType: checker is not a function Check the render method of `xxx`.

looks like a bug to me … using React v0.13.3 here

just for future reference you can also get this error if a PropType is left incomplete ie.

country: PropTypes

Closing as not a common issue, and caused by wrong usage. If it comes up often, feel free to send a PR that adds better warnings.
