title: AWS Cloudwatch Client Put_Targets - Failing on Paramater Validation Unknown "LaunchType"
body: <p>I am trying to Schedule a Task for ECS Fargate using Cloudwatch Client Put_targets method. </p>
  
  <p>I am getting the following error. </p>
  
  <pre><code>ParamValidationError('Parameter validation failed:\nUnknown parameter in Targets[0].EcsParameters: "LaunchType", must be one of: TaskDefinitionArn, TaskCount\nUnknown parameter in Targets[0].EcsParameters: "NetworkConfiguration", must be one of: TaskDefinitionArn, TaskCount
  </code></pre>
  
  <p>I am thinking maybe the support for Fargate is not yet integrated ?</p>
