アップデート
バグは変化しています。今では、2 ページ目の 3 回目のヒットまで発生しませんでした。2 ページ目の 3 回目のヒットまでページネーション エラーが発生しないのは、まったく意味がありません。これはばかげているので、何が起こっているのか、トレースを調査する方法を教えてください。トレースについて詳しく説明するようにコードを変更しましたが、python はそれが何であるかを通知しません。
失敗しているのはRegionSearchだけでなく、2ページ目以降のページでも空の文字列を検索しています。最初のページでは決して起こらないので、これは何かに関係していると思われますが、cursor何が間違っているのか完全に理解できませんでしたカーソルで。例外は何も教えてくれません。「これは機能していません」というだけで、その理由については何もわかりません。処理を変更しましたが、エラーに関する出力はこれ以上生成されませんでした: `return
index.search(query)
except search.Error as e:
logging.exception('Search failed %s', e)`
タイムアウトのように見えずにランダムに発生し、例外は問題について通知しません。「検索に失敗しました」と失敗したクエリ、検索フィールドに入力すると機能するクエリだけです。だからどう考えても無理。
