Description of the problem, including code/CLI snippet

I followed the API documentation which says that the usage of label_id, milestone_id and assignee_id is mutually exclusive. So I wanted to create a board which would relate on milestones to have a timeline. The function goes like:

def create_board(repository):
  milestones = repository.milestones.list()
  for milestone in milestones:
    print(f'ID: {milestone.id}')
    timeline_board.lists.create({
      'milestone_id': milestone.id
    })

Expected Behavior

Normally the board should be created according to the documentation.

Actual Behavior

AttributeError: Missing attributes: label_id
