Lambda 7.15.0 changes the behavior of ":zip" command: CWD instead of path is zipped

[uncatchable-de]

Description

Version 7.15 changed the behavior of the ":zip" command. In version 7.14, it zipped the path specified in the "path" attribute; In version 7.15 it zips the current working directory. This is a non-backward-compatible change.

The issue is caused by setting the _path variable to None in Version 7.15, while it previously contained the path attribute:

• https://github.com/terraform-aws-modules/terraform-aws-lambda/blob/v7.14.0/package.py#L774

This was introduced by PR 640.

Versions

• Module version [Required]: 7.15.0

• Terraform version:
  Terraform v1.9.8

• Provider version:

• provider registry.terraform.io/hashicorp/aws v5.77.0
• provider registry.terraform.io/hashicorp/external v2.3.4
• provider registry.terraform.io/hashicorp/local v2.5.2
• provider registry.terraform.io/hashicorp/null v3.2.3
• provider registry.terraform.io/hashicorp/random v3.6.3

Reproduction Code [Required]

Assume the following Lambda module source_path configuration:

   source_path = [
     {
      path = "${path.module}/application/src"
      commands = [
        ":zip",
      ]
    }
  ]

In version 7.14, this leads to a builds/plan.json file with this step:

        [
            "zip:embedded",
            "application/src",
            null
        ],

In version 7.15, this results in the following step:

		[
            "zip:embedded",
            null,
            null
        ],

Steps to reproduce the behavior: -

Expected behavior

The provided path is respected and only that is zipped. This is also shown in the README.md:

	path     = "src/python-app3",
    commands = [
      "npm install",
      ":zip"
    ],
    patterns = [
      "!.*/.*\\.txt",    # Skip all txt files recursively
      "node_modules/.+", # Include all node_modules
    ],

Actual behavior

The current working directory is zipped. In combination with Terragrunt, it results in a 5GB large Zip file, which cannot be zipped in a reasonable time.
