I'm trying to use Cyberduck CLI for uploading/downloading files from Amazon S3 bucket.
But I'm unable to formulate the correct S3 url. Below is what I've tried so far for listing the bucket contents.
C:\>duck --list s3://<bucketname>.s3-<region>.amazonaws.com/<key> --username <access_key> --password <secret_key>
But I'm getting the error:
Listing directory failed. Java.lang.NullPointerException.
Please contact your web hosting service provider for assistance.
Can you please advise if there is any issue with the s3 URL?
Cyberduck version - 4.8
The documentation mentions to
reference the target container (aka bucket) name in the URI like
s3://bucketname/key.
This means the region specific hostname s3-<region>.amazonaws.com can be omitted.
