尝试使用CopyObject修饰/重新处理S3对象

Question

我正在尝试使用copy_object来修饰或替换s3中的相同文件，我收到以下错误，我不确定我的代码中缺少什么。

我收到以下错误：

An error occurred (NoSuchKey) when calling the CopyObject operation: The specified key does not exist.: NoSuchKey
Traceback (most recent call last):
File "/var/task/S3_Reprocessing.py", line 109, in lambda_handler
s3.copy_object(Bucket=bucketName, Key=Object_to_reprocess, CopySource=copy_source)
File "/var/runtime/botocore/client.py", line 253, in _api_call
return self._make_api_call(operation_name, kwargs)
File "/var/runtime/botocore/client.py", line 557, in _make_api_call
raise error_class(parsed_response, operation_name)
NoSuchKey: An error occurred (NoSuchKey) when calling the CopyObject operation: The specified key does not exist.

            src_object = bucketName + Object_to_reprocess

            # s3.Object(bucketName, Tgt_folder).copy_from(CopySource=Object_to_reprocess, ServerSideEncryption='AES256')

            copy_source = {'Bucket': bucketName, 'Key': Object_to_reprocess}

            s3.copy_object(Bucket=bucketName, Key=Object_to_reprocess, CopySource=copy_source)
