title: CloudFormation template not updating after CDK deployment
body: <p>I have a generated Swagger json file. I have a CDK app that reads in this file and then I do</p>
  <pre><code>const cfnRestApi = this.api.node.defaultChild as apigateway.CfnRestApi;
  
  cfnRestApi.body = JSON.parse(JSON.stringify(swaggerDefinition));
  </code></pre>
  <p>After doing cdk deploy when I look at the Cloud Formation template it contains my Swagger info. However when I make changes to the Swagger json file, the template in CloudFormation is not updating even after cdk deploy runs successfully. How can I resolve this?</p>
