Help us understand the problem. What is going on with this article?

[Python3 / mongodb] pymongo で pymongo.errors.BulkWriteError: batch op errors occurred が発生した理由

pymongo.errors.BulkWriteError: batch op errors occurred

document を insertするときに、既に存在している _id と重複する _id の値を指定してしまっていた。

参考

とはいえ、他の理由でこのエラーが発生することもあると思うので、エラーを補足するのがよさそう。

try:
    # mongodbへのアクセス処理(エラー発生個所)
except pymongo.errors.BulkWriteError as error:
    print(error.details)
    # 以下のようにして、これを使うと更に詳しく調査できるらしい
    # werrors = error.details['writeErrors']
    raise

stackoverflow の Mongodb bulk write error を参考にしました

補足
