title: Swagger Can't read from file schemaValidationMessages
body: <p>I'm and tottaly new at Swagger and I'm trying to make my swagger documentation but I'm facing a problem here. I found a lot a questions similar to mine, but o couldn't understand what am I supposed to do to resolve this. The thing is, have already downloaded my swagger.json and swagger.yaml from the Swagger Editor, and followed the instructions in the <a href="https://swagger.io/docs/swagger-tools/#download-33" rel="nofollow noreferrer">Swagger Instructions</a> I tried changing the default API, but i get this error:</p>
  
  <p><a href="https://i.stack.imgur.com/sr8Em.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/sr8Em.png" alt="enter image description here"></a></p>
  
  <p>and if I click in ERROR i get this message: <code>{"schemaValidationMessages":[{"level":"error","message":"Can't read from file swagger.json"}]}</code></p>
  
  <p>I've searched here and in the internet, and I saw that people recommend disabling the validator in the index.html, but I couldn't find this options. </p>
  
  <p>Here is my <code>index.html</code> code:</p>

  <p>The PetStore example worked fine when it was installed, so no problems in the installation. I'm looking for instructions here, I can't seem to find my way around this. How can I configure this so I can see my swagger.json or swagger.yaml?</p>
