AWS S3 bucket policy for Get object error in the policy generator Json code

Question

The below code was generated by using the S3 policy generator. when I paste the code into the AWS S3 edit policy console it shows an error.

{
  "Id": "Policy1611491895768",
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "Stmt1611491893687",
      "Action": [
        "s3:GetObject"
      ],
      "Effect": "Allow",
      "Resource": "arn:aws:s3:::aws-landing-zone-configuration-756692330110-ap-south-1",
      "Principal": {
        "AWS": [
          "\"AWS\": \"arn:aws:iam::756692330110::user/aravindkumar.s@gmail.com\""
        ]
      }
    }
  ]
}

How do I overcome this error?
