Calling Custom Function Stack from Lambda with Promisify Library

Hi Xano Community,

I’m trying to call a custom function stack that I’ve created through a Lambda function in Xano. I'm using the promisify library for handling asynchronous operations.

Could anyone guide me on how to properly invoke a custom function stack from within a Lambda function? Any examples or tips on integrating promisify with Xano's Lambda functions would be greatly appreciated.

Thanks in advance!
