An error occurred (NoSuchKey) when calling the GetObject operation: The specified key does not exist.

Last updated at Posted at 2021-11-04

#エラーの訳
指定されたキーは存在しないよ

#コード

bucket_name = 'xxx'
object_key_name = 'xxx.json'
s3 = boto3.resource(
                's3',
                region_name='ap-northeast-1',
                aws_access_key_id = 'xxx',
                aws_secret_access_key = 'xxx',
            )

bucket = s3.Bucket(bucket_name)
obj = bucket.Object(object_key_name)

response = obj.get()
body = response['Body'].read()
    
json.loads(body.decode('utf-8'))

#エラー

An error occurred (NoSuchKey) when calling the GetObject operation: The specified key does not exist.

#解決方法
解決方法は、キーを見直すこと。
キー≒パス≒ディレクトリ
したがって、ディレクトリを見直すこと。一文字違ってもダメ。

エラー発生原因は非常にシンプル。ディレクトリが違うから。
ここでいうと、
object_key_name
の事になる。
例えば
aaa/bbb/ccc/ddd.json
を持ってきたいのに
aaa/bbb/ccc/eee.json
を指定していると上記のエラーが発生する。
