title: Dredd - Getting error when parsing swagger file 'API description parser warning in'
body: <p>I've recently upgraded Dredd from version 4.8 to 8+, and started getting the dozens of theses errors when Dredd attempts to parse the Swagger and generate the transaction request body. Each error is about a different row in the swagger file.</p>
  
  <pre><code>warn: API description parser warning in /builds/swagger.yaml:64 (from line 64 column 8 to line 66 column 6): Unable to generate application/json; charset=utf-8 example message body out of JSON Schema
  </code></pre>
  
  <p>Unfortunately, I'm unable to share the swagger file.
  But Dredd does manage to generate the request headers just fine.</p>
  
  <p>This is the general settings of the swagger file:</p>
  
  <pre><code>swagger: '2.0'
  info:
    version: '3'
    title: 'API'
  schemes:
  - 'http'
  consumes:
  - application/json; charset=utf-8
  produces:
  - application/json; charset=utf-8
  </code></pre>
  
  <p>The swagger file did not change between Dredd version upgrades.
  Please advise on what can be the cause.</p>
