An organization is using Amazon API Gateway to provide a public API called Survey for collecting user feedback posts about its products. The survey API has DEV and PROD stages and consists of one resource /feedback which allows users to retrieve/create/update single feedback posts.

A version-controlled Swagger file is used to define a new API that retrieves multiple feedback posts. To add the new API resource /listFeedbackForProduct the developer makes changes to the Swagger file defining an API, uploads the file to the organization s version control system, and uses the API Gateway Import API feature to apply the changes to the Survey API. After successful import, the developer runs the tests against the DEV stage and finds that resource /listFeedbackForProduct is not available.

What is MOST likely the reason for resource not being available?
