Goal:
After updatering react-router-dom from version 4 to 6 you should be enable to use this.props.match.params.id in the class PostItem

Problem:
After updatering the react-router-dom to 6 you are not enable to use this.props.match.params.id in the class PostItem in order to display value 11.

What part of the code needs to be changed in order to display the value of the parameter in the class PostItem?
