title: How to fix "mapping values are not allowed in this context " error in yaml file?
body: <p>I've browsed similar questions and believe i've applied all that i've been able to glean from answers.</p>
  
  <p>I have a .yml file where as far as I can tell each element is formatted identically. And yet according to <a href="http://www.yamllint.com/" rel="noreferrer">YamlLint.com</a> </p>
  
  <p><code>(&lt;unknown&gt;): mapping values are not allowed in this context at line 119 column 16</code></p>
  
  <p>In this case, line 119 is the line containing the second instance the word "transitions" below. That I can tell each element is formatted identically. Am I missing something here? </p>
  
  <pre><code>  landingPage:
      include: false
      transitions:
        -
          condition:location
          nextState:location
  
    location:
      include:false
      transitions:
        -
          condition:excluded
          nextState:excluded
  
    excluded:
      include:false
      transitions:
        -
          condition:excluded
          nextState: excluded
        -
          condition:age
          nextState:age
  
  </code></pre>
