I got info about the board’s columns through the API.

There was a column with the type board-relation.

{

  "id": "connect_boards",

  "title": "Deals",

  "type": "board-relation",

  "settings_str": "{\\"boardIds\\":"2816754151,2816754217],\\"boardId\\":2816754151}"

}

There are “boardIds” and “boardId” in the settings_str.

What do they mean and what is the difference between them?
