aws s3 boto3 copy()

Question

I am trying to execute the following program and facing this issue

botocore.exceptions.ClientError: An error occurred (404) when calling the HeadObject operation: Not Found

import boto3
s3 = boto3.resource('s3')
copy_source = {
    'Bucket': 'forw',
    'Key': 'test'
}
s3.meta.client.copy(copy_source,Bucket='copybucket0526',Key='tet')

You need to provide more information. What do you want to achieve? What exactly is it you are asking? — petezurich, May 26 '19 at 18:27
Do you have a bucket called `forw` that contains an object called `test`? — John Rotenstein, May 27 '19 at 00:46
Typical boto3 newbie mistake of declare boto3 s3 service resources and then use the low level service client `s3.meta.client.copy` . (or is it came from one of the bad AWS boto3 documentation example) — mootmoot, May 28 '19 at 07:50
@mootmoot bad boto3 documentation https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/s3.html#S3.Client.copy — Vinay, Oct 10 '19 at 11:35

Try this code it will work

import boto3
s3 = boto3.resource('s3')
copy_source = {
    'Bucket': 'source_bucket',
    'Key': 'dirname/subdirname/filename.gz'
}
s3.meta.client.copy(copy_source,Bucket='destination_bucket',Key='somedirname/new_or_same_filename.gz')

This is working I guess you are wrong in providing the path, means here you need to provide file complete path

In general a 404 code on HeadObject means that the resource does not exist.

in the place of key make sure the you are taking care of parent folder or sub directories(if any) of the file you are going to copy from the source bucket.

copy_source = {
    'Bucket': 'forw',
    'Key': 'top_directory/sub_directory/file.jpg'
}
