Unable to add versioning_configuration for multiple aws s3 in terraform version 4.5.0

Question

Trying to create multiple AWS s3 buckets using Terraform with the below-provided code. Provider Version: 4.5.0

Tried without count function and with for_each function as well

resource "aws_s3_bucket" "public_bucket" {
  count = "${length(var.public_bucket_names)}"
  bucket = "${var.public_bucket_names[count.index]}"
  # acceleration_status = var.public_bucket_acceleration

  tags = {
    ProjectName        = "${var.project_name}"
    Environment        = "${var.env_suffix}"
  }
}


resource "aws_s3_bucket_versioning" "public_bucket_versioning" {

  bucket = aws_s3_bucket.public_bucket[count.index].id 

  versioning_configuration {
    status =   "Enabled"
  }
}

Facing below error

 Error: Reference to "count" in non-counted context
│ 
│   on modules/S3-Public/s3-public.tf line 24, in resource "aws_s3_bucket_versioning" "public_bucket_versioning":
│   24:   bucket = aws_s3_bucket.public_bucket[count.index].id 
│ 
│ The "count" object can only be used in "module", "resource", and "data" blocks, and only when the "count" argument is set.

Your current code creates multiple S3 buckets, but only attempts to create a single bucket versioning configuration. You are referencing a count variable inside the bucket versioning resource, but you haven't declared a count attribute for that resource yet.

You need to declare count on the bucket versioning resource, just like you did for the s3 bucket resource.

resource "aws_s3_bucket_versioning" "public_bucket_versioning" {
  count = "${length(var.public_bucket_names)}"
  bucket = aws_s3_bucket.public_bucket[count.index].id 

  versioning_configuration {
    status =   "Enabled"
  }
}
