title: Terraform JSON "At 1:1: illegal char" error
body: <p>When attempting to run <code>terraform init</code> with a JSON I keep getting the error:</p>
  
  <pre><code>There are some problems with the configuration, described below.
  
  The Terraform configuration must be valid before initialization so that
  Terraform can determine which modules and providers need to be installed.
  
  Error: Error parsing C:\terraform\terraform.tf.json: At 1:1: illegal char
  </code></pre>
  
  <p>The JSON is valid and the HCF version works as expected. What is wrong?</p>
