sam package is reducing the size of my template

问题

I have a SAM template that I am using to building 4 lambda functions integrated with API gateways.

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: An AWS Serverless Specification template describing your function.

the next step after this to package and deploy the code.

I am using aws cloudformation package as it is similar to sam package and I have tried both.

As soon as I run the command the template file gets reduced. from 100 lines to 50 lines. when I observe the middle two functions are being omitted.

don't exactly know the reason for this. Is there any limit on the number of functions? or I am missing anything?

回答1:

two functions are being omitted.

The functions are skipped because they have same name of GetUserProfile. So one overwrites the other as you have three of them. You have to rename them:
