As you are parsing JSON in constructor itself. there is no need to call setState , you can directly assign state.

Try this:

constructor(props) {
  super(props);    

  var text = JSON.parse(jobs);
  this.state = {
    Vehicle_Details: text.map(function(item) {
      return item['Vehicle_Details']
    })
  }
}
