Checkov fails to parse tf.json sources and returns an error to the console

Describe the bug When executing checkov against a directory with tf.json sources, an error is produced with the following message

       _               _

Error parsing file /Users/marco.ferrer/my-project/cdk.tf.json

The contents of cdk.tf.json are as follows

{
  "variable": {
    "environment": {
      "type": "string"
    },
    "aws_region": {
      "default": "us-east-1",
      "type": "string"
    },
    "aws_profile": {
      "type": "string"
    }
  },
  "terraform": {
    "required_providers": {
      "aws": {
        "version": "~> 2.70.0",
        "source": "aws"
      }
    }
  },
  "provider": {
    "aws": [
      {
        "profile": "${var.aws_profile}",
        "region": "${var.aws_region}",
        "alias": "default"
      },
      {
        "profile": "external",
        "region": "us-west-1",
        "skip_requesting_account_id": true,
        "alias": "external"
      }
    ]
  },
  "resource": {
    "aws_secretsmanager_secret": {
      "local-secret": {
        "name": "internal-secret",
        "provider": "aws.default"
      },
      "external-secret": {
        "name": "external-secret",
        "provider": "aws.external"
      }
    }
  }
}

To Reproduce Steps to reproduce the behavior:

1. Create a new directory
2. Within this directory, create a new file with the suffix .tf.json
3. Populate the file with the json example from above or any other valid tf.json definition
4. Execute checkov -d ./path/to/your/new/directory
5. Review cli output for the parsing error

Expected behavior The expected result is for the modules sources to be properly parsed and the built-in checkov rules asserted over the content of the tf.json sources.

Desktop (please complete the following information):

• OS: macOSX 10.15.5
• Checkov Version 1.0.716 and earlier

@robeden - It seems to have resolved all my issues, thanks 😃

~@chrisbloe - tfvars problems should be fixed as of a couple days ago (see #865).~

Well, maybe not given the type of error being reported. I think that’s a separate issue from this ticket, so you might want to post a sanitized data sample here or in another ticket, if possible.
