APIs get removed when deploying
This issue might occur when you do not have the latest API Gateway rules in your local system. So when you deploy your code, the API Gateway rules are also deployed and since that rule is not present in your local system, it gets removed from the catalyst console. We would suggest you to do catalyst pull in order to pull all the latest API Gateway rules to your system and then deploy your code in order to resolve your issue. You can find the help documentation for the same here. Do check on the same and let us know if you further face any issues.
