Props is missing from props validation

I'm using the following code which is being parsed by the linter eslint-plugin-react. It returns the warning:

"product is missing in props validation"

while i declare product in propTypes at the bottom and that i pass it to function. any idea ?

import React from 'react'

const ProductDesc = (props)=>({
  render(){
    return (
      <div>
        <h1>{props.product.headline}</h1>
        <img src={props.product.images[0].imagesUrls.entry[2].url} alt="Thumbnail large pic"/>
        <p>Yeah</p>
      </div>
    )
  }
})

ProductDesc.propTypes = {
  product: React.PropTypes.object
};

export default ProductDesc;
