    forum.addPost(post);

  }

You seem to have removed the getters from the ForumPost class. The code will break without them. Try adding them back. You also renamed the method 'getTopic()' in 'setTopic()' in the Forum class. If you change anything else than what you're asked to change, the automatic tests that check your answers might no longer run correctly.

  public User getAuthor() {
    return author;
  }

  public String getTitle() {
    return title;
  }

  public String getDescription() {
    return description;
  }

i never removed them and the assignment didn't asked me to create them , i tried adding them back and it didn't work

thanks for your help

You're not supposed to create them, but they should be there from the start. Try completely restarting the challenge, and adding back only the code needed for each step. I tried the challenge adding snippets from your code and it passed. You're correct that you did everything right.
