Python/Kivy：ValueError：TreeViewLabelAccountGroup.textはstrのみを受け入れる

Question

私はPython（test.py）とkivy（test.kv）でいくつかのコードを書いています。test.py.thenを実行するとテストメニューとユーザサブメニューが表示されます。ユーザーをクリックすると、+ボタンを追加します。+をクリックすると、Number TextBox Typeが表示されます。
数字のテキストボックスでtreeViewを使用しています。選択番号をクリックするとエラーが発生します
kivy._event.EventDispatcherのファイル "kivy/_event.pyx" 273行目。 init（kivy/_event.c：5375） kivy.properties.Propertyのファイル "kivy/properties.pyx"、行478。 セット（kivy/properties.c：517​​1） kivy.properties.Property.set（kivy/properties.c：5882）のファイル "kivy/properties.pyx" 513行目 ValueError：TreeViewLabelAccountGroup.textのみ受け入れるstr

rows = [（1、111）、（2、112）]の代わりにrows = [（1、 'Male'）、（2、 'Female'）、（3、 'Dog' ）、（3,113）]
それは正常に動作します。
私はどこで間違いをしているのか分かりません。
テキストをintに変更すると、そのテキストは動作しますがデータは表示されません。

if parent is None: 
      tree_node = tree_view_account_group.add_node(TreeViewLabelAccountGroup(text=node['node_id'], 
                 is_open=True)) 
     else: 
      tree_node = tree_view_account_group.add_node(TreeViewLabelAccountGroup(text=node['node_id'], 
                 is_open=True), parent)

Answer 1

あなたはstrにnode_idを変換する必要があります。

for r in rows: 
    treeAccountGroup.append({'node_id': str(r[1]), 'children': []})
