Package 'individually=true' not working when setup at function level and 'false' at service level

[bruno-xo7]

Hello,

I got an issue with the package 'individually' not working. I have setup a simple project to easily test it:

• serverless.yml:

service: sls-ts-package-individually
frameworkVersion: "3"
configValidationMode: error

plugins:
  - serverless-plugin-typescript

provider:
  name: aws
  runtime: nodejs18.x
package:
  individually: false
  patterns:
    - src/**

functions:
  one:
    handler: src/main.handler1
  two:
    handler: src/main.handler2
  three:
    handler: src/main.handler3
    package:
      individually: true
      patterns:
        - "!src/not_included_in_3"

• package.json

{
    "name": "test-sls-ts-package-individually",
    "version": "1.0.0",
    "description": "To test package individually",
    "license": "UNLICENSED",
    "private": true,
    "scripts": {
        "build": "tsc"
    },
    "devDependencies": {
        "@types/aws-lambda": "^8.10.131",
        "@types/node": "^18.11.9",
        "serverless": "^3.38.0",
        "serverless-plugin-typescript": "^2.1.5",
        "typescript": "~4.7.4"
    },
    "dependencies": {}
}

• src/main.ts

import { Handler } from "aws-lambda";

export const handler1: Handler = async () => {
    console.info("Hello function one!");
};

export const handler2: Handler = async () => {
    console.info("Hello function two!");
};

export const handler3: Handler = async () => {
    console.info("Hello function three!");
};

• It also need a file named src/not_included_in_3

Then when I type sls package, I got this error:

Running "serverless" from node_modules

If I disable the plugin serverless-plugin-typescript it's working fine. And I got 2 package in .serverless directory without error:

• sls-ts-package-individually.zip
• three.zip

Can this be fixed?

Thank you,
Bruno

just watching, have similar issue

@bruno-xo7 I apologize, maybe it's wrong, but according to the documentation on the service level individually should be true:

...
package:
  individually: true
...

and remove individually from function level:

...
  three:
    handler: src/main.handler3
    package:
      patterns:
        - "!src/not_included_in_3"
...

[a-khalilov]

@bruno-xo7 But in my case I have the same warning as you, but I configure package on service level, and don't use individual at all

...
package:
  excludeDevDependencies: true
  patterns:
    - '!node_modules/serverless*/**'
    - '!node_modules/aws_sdk/'
    - '!package-lock.json'
...    

VSCode plugin says (regarding the same documentation article mentioned in the comment above) that the package block should be on provider level ((

Hello @a-khalilov,

What you describe, it's to have 3 individual packages (in my example), one for each function. My problem is not this case, I want to have one 'global' (a.k.a. not individual) package for functions 'one' and 'two' and one individual package for the function 'three'. This is why I set the 'individually' at false at service level and true at the function 3 level.

@bruno-xo7 I see. You're right, I didn't understand your case correctly.
But I can confirm, that with my config I tried to reproduce your case and got 2 packages and the error.
I'm guessing that the error makes your pipeline fail. Because I've seen both packages and they're correct

[bruno-xo7]

Correct @a-khalilov, It's failed at the package step and indeed the deploy is not launched because of the fail

[a-khalilov]

@bruno-xo7 I got your problem. Had something similar with other serverless plugins. I use some pipes as a workaround, something like
sls package | tee /dev/tty | grep -q 'anything of command's output that you would like to use as a condition' && exit 1
I'm sure you found a workaround, but anyway maybe it'll be useful for others
Cheers!
