Could not locate source_path "null" despite create_function = false #409

Closed DuncanKwokTR closed 1 year ago

DuncanKwokTR commented 1 year ago

Description

I already have zipped my own package and do not require create_function, so it is set to false. Yet despite that, module is looking to for source_path of the deployment. It is already given local_existing_package = "file.zip"

module "r53_lambda_function_externally_managed_package" { source = "../../Resource_modules/lambda/" create_function = true # to control creation of the Lambda Function and related resources create_package = false # to control build package process create_layer = false # to control creation of the Lambda Layer and related resources create_role = true # to control creation of the IAM role and policies required for Lambda Function

function_name = local.vds_lambda_function_name description = "My lambda function code is deployed separately" handler = var.vds_lambda_handler runtime = var.vds_lambda_runtime ignore_source_code_hash = true vpc_security_group_ids = [module.r53_security_group.security_group] vpc_subnet_ids = var.vds_lambda_subnet_ids

attach_cloudwatch_logs_policy = false attach_dead_letter_policy = false attach_network_policy = false attach_tracing_policy = false attach_async_event_policy = false

local_existing_package = var.vds_lambda_filename

Depsite asking not to create package...

source_path = local.source_path

source_path = "../../../lambda_python/healthcheck.zip"

// IAM Role Create role_path = local.iam_lambda_role_path role_name = local.iam_lambda_role_name role_description = local.iam_lambda_role_description role_permissions_boundary = local.iam_lambda_role_permissions_boundary_arn role_force_detach_policies = local.iam_lambda_force_detach_policies

// IAM Policy Create policy_name = local.iam_lambda_policy_name policy_path = local.iam_lambda_policy_path policy_json = local.iam_lambda_policy

// IAM Policy Attachment attach_policy_json = true

}

Looking at the main.tf module, I see only 2 references to source_path resource "null_resource" "sam_metadata_aws_lambda_function" { count = local.create && var.create_package && var.create_function && !var.create_layer ? 1 : 0

resource "null_resource" "sam_metadata_aws_lambda_layer_version" { count = local.create && var.create_package && var.create_layer ? 1 : 0

To my understanding, if create_package = false, source_path should not even be required and will be null.

⚠️ Note

Before you submit an issue, please perform the following first:

  1. Remove the local .terraform directory (! ONLY if state is stored remotely, which hopefully you are following that best practice!): rm -rf .terraform/
  2. Re-initialize the project root to pull down modules: terraform init
  3. Re-attempt your terraform plan or apply and check if the issue still persists

Versions

Steps to reproduce the behavior:

no yes

call the resource module to create lambda function that has externally managed package and don;t build it from source.

Expected behavior

Skip the creation of the package.

Actual behavior

it is looking asking for source_path, despite create_function = false.

Terminal Output Screenshot(s)

│ Error: External Program Execution Failed │ │ with module.r53_lambda_permission.data.external.archive_prepare[0], │ on ../../Resource_modules/lambda/package.tf line 10, in data "external" "archive_prepare": │ 10: program = [local.python, "${path.module}/package.py", "prepare"] │ │ The data source received an unexpected error while attempting to execute the program. │ │ Program: /usr/local/bin/python3 │ Error Message: Could not locate source_path "null". Paths are relative to directory where terraform plan is being run │ ("/home/users/gitprojects/Infrastructure_modules/cloud_container_infrastructure")

It says paths are relative, but in variables.tf, it says absolute path. variable "source_path" { description = "The absolute path to a local file or directory containing your Lambda source code" type = any # string | list(string | map(any)) default = null }

I've also tried to set create_function = true but it can never find my source through source_path even though it is correct.

Additional context

Apologies, in my original post, i wrote source_path = "../../../lambda_python/healthcheck.zip" It is supposed to be simply source_path = "../../../lambda_python" but still didnt work.
