My attribute values are saved as NULL

[PavanOnRails]

I have a PostResource with title, upvotes and active as attributes. I'm making POST api call with the data as such

{"post":{
  "title": "example1234",
  "upvotes": 67,
  "active": true
}
}

But the values for title, upvotes and active are always saves as NULL in the database. Can you help me solve this.

Here is my controller create action

def create
    post_params = params.require(:post).permit(:title, :upvotes, :active)
    @post = PostResource.build(post_params)
    byebug
    if @post.save
      render jsonapi: @post, status: 201
    else
      render jsonapi_errors: @post
    end
  end

And here is output from debugger
