It allows the IAM entity to list all of the bucket’s objects. The S3 error ” when calling the PutObject operation” occurs when we try to upload a file to an S3 bucket without having the necessary permissions. When your data is being encrypted in S3, it could be done via a KMS key which your user would need access to as well to decrypt the objects. Find out what role you are using and double check the permissions. If this is not a root account, ask your administrator.

Don’t attach this policy as a bucket policy. Rather attach it to the user that is trying to upload files to the S3 bucket or to the corresponding role (e.g. of a lambda function or EC2 instance).

Unable to grant public access to an existing S3 bucket?

If your IAM policy is configured correctly and you still can’t access your S3 bucket, there might be an issue with the Bucket Policy. A common mistake is to only provide permissions to objects within the bucket. You want to ensure that you give permissions to the bucket itself. We allowed the GetObject and ListObject actions to a specific user in the account . The first statement in the JSON policy allows the GetObject action on individual objects in sub-directories of the bucket. Once the policy is attached to the IAM entity, you will be able to upload files to your S3 bucket.

Furthermore, check if there is a condition that permits only a particular IP range to access bucket objects. However, if the user or role belongs to the bucket owner’s account, we need permission only from IAM or the bucket policy.


As the key pair is created, save the new credentials to a safe place for further use. LIA InfraServices goes the extra mile, in more ways than one, to support your IT needs. Making statements based on opinion; back them up with references or personal experience. So Simply add a S3 Policy to you IAM User as in below screenshot , mention your Bucket ARN for make it safer and you don’t have to make you bucket public again. If you have an encrypted bucket, you will need kms allowed. Share a link to this question via email, Twitter, or Facebook.

If you are uploading files and making them publicly readable by setting theiracl to public-read, verify that creating new public ACLs is not blocked in your bucket. AWS S3 is one of the main infrastructure components that is the foundation for many Data Lake designs. As a result, being a Data Engineer, you will most likely come across this being used in some way, shape or form have to interact with it to push or pull data. Now, throughout my time, I have run in various issues with accessing data, especially relating to Access Denied.

  • We just went on an interesting journey of finding what permissions are actually required to put an object in S3 using Spark.

The Access Denied error occurs due to not having the required permissions to perform actions on the bucket. Fortunately, there is an easy resolution AWS S3 ListObjects operation Access Denied error. The S3 error ” when calling the ListObjectsV2 operation”occurs when we try to list the objects in an S3 bucket without having the necessary permissions.

We do not know exactly what Spark is doing with S3 until we ran into the errors. Have you ever come across this frustrating situation, when your developer suddenly asks you to enable public access to an existing private S3 bucket. You try to enable it through the console but, this gives you an error message as below. Alternatively, our AWS experts suggest verifying that the policy does not restrict access to GetObject or ListObject action.
