How to solve error in yaml/swagger?
<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>
