Fix MalformedPolicyDocumentException

✅ Solution

MalformedPolicyDocumentException in Terraform usually arises from syntax errors or invalid structure within your IAM policy documents, especially in `aws_iam_policy` resources or when using `templatefile`. Carefully review the policy JSON for correctness, ensuring valid JSON syntax, proper escaping of special characters, and that all required fields adhere to the IAM policy grammar specified by AWS. Utilize online JSON validators and the AWS IAM policy simulator to identify and rectify any inconsistencies before applying your Terraform configuration.
