title: Boto3 InvalidParameterException
body: <p>I have some code that calls into AWS's Rekognition service. Sometimes it throws this exception:</p>
  
  <pre><code>An error occurred (InvalidParameterException) when calling the DetectLabels operation: Request has Invalid Parameters
  </code></pre>
  
  <p>I can't find the <code>InvalidParameterException</code> anywhere in the documentation or code, though, so I can't write a specific handler for when that occurs. Does anyone know what library module that exception lives in?</p>
