How to access a file from the module

Terraform

I’m trying to create an S3 bucket with the policy as part of the module.
instead of EOF construct for policy, I’ve been thinking to use a file (with the policy). But I’m getting the :

Invalid function argument

What is the proper way to access another file in a module?

Code:

cat S3.tf
...
resource "aws_s3_bucket" "this" {...}
...
resource "aws_s3_bucket_policy" "SSL" {
  bucket = aws_s3_bucket.this.id
  policy = file("ssl.json")
}

in the module directory:

ls -l ../../../NGG/modules/AWS/S3/
total 8
-rwxrwx--- 1 root vboxsf 1071 Dec  9 17:24 input.tf
-rwxrwx--- 1 root vboxsf    0 Dec  9 17:24 outputs.tf
-rwxrwx--- 1 root vboxsf 1614 Dec 15 12:04 S3.tf
-rwxrwx--- 1 root vboxsf  527 Dec 15 11:58 ssl.json

on the flip side, the following code works great, but i’m not using it in the module:


resource "aws_iam_policy" "EC2_Execute" {
  description = "Policy allows a limited execution of EC2s"
  name = "EC2_Execute"
  path = "/"
  policy = file("policy/EC2-execute.json")
}

You need to use ${path.module} as part of the path so that it can find the file correctly.
