s3 bucket i m getting an error please help me to resolve this

Hi Meghana,

Please set the credentials of the IAM user that you want to use [1].
If you have a named profile set, you can run the profile name:

export AWS_PROFILE=profile-name

If not you can export the credentials by referring to this [2].
Hope this resolves your issue. If not, please mention the issue.
