Importing multiple AWS S3 buckets using for_each

Hi all,
I am trying to import multiple S3 buckets using the import block. Also I don’t want to use import command but want to execute using normal procedure of Init, Plan & Apply. I am trying to use for_each loop for this but getting error. Below is the code from terraform site:
Site:- Import - Configuration Language | Terraform | HashiCorp Developer

Code:-
locals {
buckets = {
“staging” = “bucket1”
“uat” = “bucket2”
“prod” = “bucket3”
}
}

import {
for_each = local.buckets
to = aws_s3_bucket.this[each.key]
id = each.value
}

resource “aws_s3_bucket” “this” {
for_each = local.buckets
}
