title: How to solve error in yaml/swagger?
body: <p>This is part of my yaml schema:</p>
  
  <pre><code>paths:
    '/testing/all':
      get:
              summary: Get list of open items
              tags:
                - Items
              description: |
                Returns an array of json objects items
              responses:
                '200':
                      description: Array of open items
                      schema:
                          type: array
                          $ref: '#/definitions/itemList'
                  default:
                      description: Unexpected error
                      schema:
                          $ref: '#/definitions/Error'
  </code></pre>
  
  <p>I am aware of the indentation but still there is an error on the line which contains 'responses':</p>
  
  <pre><code>YAMLException: can not read a block mapping entry; a multiline key may not be an implicit key at line 20, column 13:
                          responses:
  </code></pre>
  
  <p>How can I fix this error, I am using webstorm 2016 and windows 7?</p>
