Versions

• Module version [Required]: 6.5.0

• Terraform version: 1.5.7

• Provider version(s):

• provider registry.terraform.io/hashicorp/aws v5.31.0

• provider registry.terraform.io/hashicorp/external v2.3.2

• provider registry.terraform.io/hashicorp/local v2.4.1

• provider registry.terraform.io/hashicorp/null v3.2.2

Reproduction Code [Required]

module "lambda" {
  source  = "terraform-aws-modules/lambda/aws"
  version = "6.5.0"
}

# ...

module "lambda_function" {
  source = "terraform-aws-modules/lambda/aws"

  function_name = "easteregg"
  handler       = "app.lambda_handler"
  runtime       = "nodejs20.x"

  role_name = "easteregg"

  source_path      = "${path.module}/../src"

}

Steps to reproduce the behavior:

Expected behavior

• source_path should not be none
• role_names should be valid

Actual behavior

• source_path seems to be none

Additional context

This is happening on Windows

I encountered some issues related to source_path when I updated to release v7.0.0 while using aws provider version 5.24.0, I'm not saying this will solve your issues but in my case a bunch of errors went away when I updated the aws provider to version 5.33.0

[antonbabenko]

This code is wrong because there are not enough variables specified:

module "lambda" {
  source  = "terraform-aws-modules/lambda/aws"
  version = "6.5.0"
}

Please take a look at the examples for real and working examples.
