Describe the issue
Explain what you expected to happen when checkov crashed.

When I use checkov to scan Terraform S3 public module v4.2.2, checkov throws some errors:

• Terraform S3 module: https://registry.terraform.io/modules/terraform-aws-modules/s3-bucket/aws/latest

Exception Trace

checkov -d . --compact --quiet
