It does work on my account. Did you check:

• the board has at least one subitem


• the columnId of the subitem column mitht be different

Alternatively, this would work without hardcoding the columnId

{

  boards(ids: $(boardId)) {

    columns(types: [subtasks]) {

      settings_str

    }

  }

}

For some reason, some of my boards have multiple settings_str values.

Example query:

query test {boards(ids:<BOARD_ID>)

  {

    columns

    {settings_str}

  }

}

Output:

{

  "data": {

    "boards": [

      {

        "columns": [

          {

            "settings_str": "{}"

          },

          {

            "settings_str": "{\\"allowMultipleItems\\":true,\\"itemTypeName\\":\\"column.subtasks.title\\",\\"displayType\\":\\"BOARD_INLINE\\",\\"boardIds\\":[xxxxxxx]}"

          },

          {

            "settings_str": "{}"

          },

          {

            "settings_str": "{\\"done_colors\\":[1],\\"labels\\":{\\"0\\":\\"Working on it\\",\\"1\\":\\"Done\\",\\"2\\":\\"Stuck\\"},\\"labels_positions_v2\\":{\\"0\\":0,\\"1\\":2,\\"2\\":1,\\"5\\":3},\\"labels_colors\\":{\\"0\\":{\\"color\\":\\"#fdab3d\\",\\"border\\":\\"#e99729\\",\\"var_name\\":\\"orange\\"},\\"1\\":{\\"color\\":\\"#00c875\\",\\"border\\":\\"#00b461\\",\\"var_name\\":\\"green-shadow\\"},\\"2\\":{\\"color\\":\\"#df2f4a\\",\\"border\\":\\"#ce3048\\",\\"var_name\\":\\"red-shadow\\"}}}"

          },

          {

            "settings_str": "{}"

          }

        ]

      }

    ]

  },

  "account_id": XXXXX

}

You are requesting the setting_str for each column on your board. The board itself does not have a setting_str. If you want to limit to the subtask column you should filter it in your request

query test {boards(ids:<BOARD_ID>)

  {

    columns (types: [subtasks])

    {settings_str}

  }

}
