Hi Pritha,

I have added the bucket to the resource, but I am still running into the same Forbidden response.

Thanks,
Austin

Hi Austin,

Can you try by adding the bucket arn to the Resource section of the policy, like the following:

"Resource": [
                                       "arn:aws:s3:::bucket1",
                                        "arn:aws:s3:::bucket1/*",
                                        "arn:aws:s3:::bucket2/*"

                                    ]

Thanks,
Pritha
