DynamoDBテーブルが部分的に更新される

Question

DynamoDBテーブルを更新しようとすると、パーティションキー値のみが更新されます。残りの値を含めると、次のエラーがポップアップします。 getterメソッドをポイントします。

logcat

私はstackoverflowの経験の投稿の多くを持っていけません。寛容にしてください:)。

EDIT：form_id以外のゲッターをコメントアウトするとき。データが更新されます。そうしないと、logcatエラーが表示されます。

最初の問題は、FeedbackFormクラスです。すべての属性は、注釈@DynamoDBHashKeyで定義されています。 ハッシュキー以外のフィールドの注釈を変更してください。通常の属性には@DynamoDBAttributeを使用してください。

@DynamoDBAttribute(attributeName = "comments") 
     public String getComments() { 
      return comments; 
     }
