[Solved] S3 Bucket action doesn't apply to any resources

This error occurred when i tried implementing the s3 bucket policy.

this is due to the following policy which i was implementing

            "Action": [
                "s3:GetBucketLocation",
                "s3:ListBucket",
                "s3:GetObject",
                "s3:PutObject"
            ],
            "Resource": [
                "arn:aws:s3:::bucketname"
            ]

The issue here is , I was trying to implement it on the bucket only when the action has to applied in the form of regex to all the objects under the bucket so i replaced it with

            "Action": [
                "s3:GetBucketLocation",
                "s3:ListBucket",
                "s3:GetObject",
                "s3:PutObject"
            ],
            "Resource": [
                "arn:aws:s3:::bucketname",
                "arn:aws:s3:::bucketname/*"
            ]

That resolved my issue.
