Question: Packaging configuration seems to be ignored

[DanEscudero]

Hi!

I'm facing some trouble when generating the package, and I think files are not being included correctly.

Setup

I'm using [email protected], and [email protected]
I have this serverless.yml:

service: jetpack-test

provider:
  name: aws
  runtime: nodejs14.x

plugins:
  - serverless-jetpack

functions:
  myFunction:
    name: 'myFunction'
    handler: main.handler
    timeout: 5

    jetpack:
      preInclude:
        - 'files/function-pre-include.txt'
        - '!files/function-pre-exclude.txt'
    
    package:
      include:
        - 'files/function-include.txt'
        - '!files/function-exclude.txt'

custom:
  jetpack:
    preInclude:
      - '!**'
      - 'files/service-pre-include.txt'
      - '!files/service-pre-exclude.txt'

package:
  include:
    - 'files/package-include.txt'
    - '!files/package-exclude.txt'

And my file structure is pretty straight-forward:

serverless.yml
package.json
node_modules
main.js
files
|__ function-pre-include.txt
|__ function-pre-exclude.txt
|__ function-include.txt
|__ function-exclude.txt
|__ service-pre-include.txt
|__ service-pre-exclude.txt
|__ package-include.txt
|__ package-exclude.txt

Excpected:

The expected should be a zip file with all *include.txt files, along with node_modules production dependencies, like so:

node_modules
files
|__ function-pre-include.txt
|__ function-include.txt
|__ service-pre-include.txt
|__ package-include.txt

Actual Result:

When running yarn serverless package, the zip file contains only this files:

node_modules
files
|__ service-pre-include-file.txt
|__ package-include-file.txt

Report

When generating report, this is what I'm getting:

I also conducted another test, but this time removing the - !**/** line from custom.jetpack.preInclude; This time, I got in the output package all files in files folder, except for service-pre-exclude and package-exclude.

This way, both of this tests show that function.{NAME}.package.include and function.{NAME}.jetpack.preInclude are being ignored; So, the question is: What am I missing? Is this a configuration issue? Or did I misunderstand the documentation?

Here, I'm leaving a repo where you can clone and test this very same repository that I used and reproduce this issue:

Thanks in advance!

So, the tricky part is for service packaging in SLS (with or without jetpack) function.NAME.include is completely ignored if you are not packaging individually: true. For example:

Where I've disabled jetpack, added a service level package.includeof !** at the start (to negate the initially added ** SLS starts with). The result is that the service level files/package-include.txt is included, but the function.myFunction.pcakge.include'ed file files/function-include.txt is not.

We end up with only one file in this case:

$ yarn sls package && zipinfo -1 .serverless/jetpack-test.zip
files/package-include.txt

Turning now to Jetpack, jetpack does the same thing -- function.NAME.jetpack.preInclude only is applicable if individually: true. So let's package that function individually instead:

diff --git a/serverless.yml b/serverless.yml
index bd741b3..84a02a2 100644

+++ b/serverless.yml

The resulting report (and zip file if you info it) now show all four of your expected include files:

$ yarn sls jetpack package --report

I would characterize this issue as: (1) expected behavior, that (2) is not well-documented either in SLS or in this plugin. Accordingly I've opened #353 to better document this.

Hopefully this helps you through your issue. I wanted to further thank you for taking the time to open up a full error reproduction repository -- it makes diagnosis and discussion of nuanced issues like these actually tractable!

[DanEscudero]

Thanks!
I added the individually: true in the package session, and it worked well!
