Can upload files but can't list S3 bucket objects. Get access denied error

Question

I\'m trying to list all the files in my S3 bucket. But constantly getting the error Access denied. I think I have the necessary permissions in my IAM user :

Answer 1

I was having same issue. I was using two machines, one was having aws profile created and I was able to list s3 bucket, but on second machine where my profile was not created and I was using Set-AWSCredential command I was not able to list s3 bucket. Moment I created profile I was able to access s3 ls.

Answer 2

Just found the answer! The Actions allowed in the policy are correct. The problem is with the Resource. I was using this :

"Resource": [
   "arn:aws:s3:::bucket/*"
]

But it looks like it does not give permission to the root of the bucket. No full access. So, to make it work, we have to remove / like this :

"Resource": [
   "arn:aws:s3:::bucket*"
]

Now it's working like a charm.
