org.sprindoc.demo.app3 BeanUtils.copyProperties method does copy all properties

[seydaz1mov]

When I start org.sprindoc.demo.app3 and post tweet. It gets TweetDTO, and returns Tweet model where id and text are null.

For example, tweetDto is:

{
  "id": "2",
  "text": "ASDSAS",
  "createdAt": "2020-01-20T10:13:08.650Z"
}. 

It will return, tweet model:

{
  "id": null,
  "text": null,
  "createdAt": "2020-01-20T10:26:13.589+0000"
}
