How to print props object in JSX, i am getting TypeError: Cannot read property of undefined

Question

I am trying to print the value of props in my JSX,even though the logs show the object when i try to print individual objects it throws error TypeError: Cannot read property <'objects'> of undefined

i am using REDUX, i tried looping using map, forEach etc. still i am getting the error. console.log("props.stories") shows the objects but when i try to log individual objects the "props.stories" becomes "undefined"

import React from 'react'
import {connect} from 'react-redux'
import {Link} from 'react-router-dom'

const ShowStory = (props) => {
    console.log(props.stories) // shows objects
    console.log(props.stories._id) // gives error and above log becomes undefined
    return(
        <div>
            <h1>{props.stories.bookTitle}</h1>
        </div>
    )
}

const mapStateToProps = (state, props) => {
    const id = props.match.params.id
    var arr1d = [].concat(...state.stories)
    return {
        stories: arr1d.find(story => story._id == id),
    }
}

export default connect(mapStateToProps)(ShowStory)

If stories is an array of objects, you need to access it using .map function like this.

Remove this line to get rid of console error:

console.log(props.stories._id) // gives error and above log becomes undefined

If you want to print all stories' bookTitle then:

<ul>
{props.stories.map((story, index) => (
                <li key={index}>{story.bookTitle}</li>
              ))}
</ul>

If you want to print first story's bookTitle then:

<div>
  <h1>{props.stories[0].bookTitle}</h1>
</div>
