CORS rules configuration on a new S3 bucket fails

[ArghyaChakraborty]

Description

I am trying to create a new S3 bucket with CORS rules configured. But Terraform fails in Plan phase with following error:
Error: Invalid count argument
on .terraform/modules/s3_interim_bucket/main.tf line 200, in resource "aws_s3_bucket_cors_configuration" "this":
200: count = local.create_bucket && length(local.cors_rules) > 0 ? 1 : 0
The "count" value depends on resource attributes that cannot be determined
until apply, so Terraform cannot predict how many instances will be created.
To work around this, use the -target argument to first apply only the
resources that the count depends on.

⚠️ Note

Before you submit an issue, please perform the following first:

1. Remove the local .terraform directory (! ONLY if state is stored remotely, which hopefully you are following that best practice!): rm -rf .terraform/
2. Re-initialize the project root to pull down modules: terraform init
3. Re-attempt your terraform plan or apply and check if the issue still persists

Versions

• Module version [Required]:

• Terraform version:

Reproduction Code [Required]

module "s3_interim_bucket" {
source = "terraform-aws-modules/s3-bucket/aws"

bucket = "some-bucket"
acl = "private"

control_object_ownership = true
object_ownership = "ObjectWriter"
force_destroy = true

block_public_acls = true
block_public_policy = true
ignore_public_acls = true
restrict_public_buckets = true

versioning = {
enabled = false
}

lifecycle_rule = [
{
id = "file"
enabled = true

  filter = {
    prefix = "file/"
  }

  expiration  = {
    days = 3
  }
}

]

cors_rule = [
{
allowed_headers = ["*"],
allowed_methods = ["GET"],
allowed_origins = ["https://corporatedns.com"],
expose_headers = []
}

server_side_encryption_configuration = {
rule = {
apply_server_side_encryption_by_default = {
