Inconsistent behaviour: re-run "terraform apply" doesn't re-create deleted project

[james-ni]

Terraform Version

1.5.6

Harness Provider Version

0.29.2

Affected Resource(s)

Only harness_platform_project is affected.

Other resource types like harness_platform_service, harness_platform_variable are behaving as expected.

Terraform Configuration Files

terraform {
  required_providers {
    harness = {
      source = harness/harness
    }
  }
}

provider "harness" {
  endpoint      = "https://app.harness.io/gateway"
  account_id  = "xxxxxxx"
}

resource "harness_platform_project" "project" {
  identifier     = "james123"
  name           = "james
  description = "james"
  org_id         = "org1"
}

Expected Behavior

When:

1. terraform init
2. terraform apply --auto-approve (this will create the project)
3. manually delete project from Harness UI
4. terraform apply --auto-approve

I'm expecting step 4 (re-run terraform apply) will create the project.

Actual Behavior

step 4terraform apply failed, with error message "404 Not Found"

This behaviour is inconsistent with other Harness resources like service, variable...

Possible root cause

Harness GET project behaves differently from other GET xxx APIs (e.g. service, variable...)

• GET project returns payload {"code": "ENTITY_NOT_FOUND"}, when a given project id doesn't exist
• GET service (or any other resources) returns payload {"code": "RESOURCE_NOT_FOUND_EXCEPTION"}, when a given service id doesn't exist

The error handling code below only handles {"code": "RESOURCE_NOT_FOUND_EXCEPTION"}, not {"code": "ENTITY_NOT_FOUND"}. That's why it failed to re-create project and error out.

terraform-provider-harness/helpers/errors.go

Lines 67 to 70 in d55c04c

	if erro.Code() == nextgen.ErrorCodes.ResourceNotFound {
	d.SetId("")
	d.MarkNewResource()
	return nil

Actually there is another exception

• GET resource_group API returns payload {"code": "RESOURCE_NOT_FOUND"}, when a given resource group id doesn't exist.

Proposed Change

• option 1: add {"code": "ENTITY_NOT_FOUND"} to the if condition, like

    if erro.Code() == nextgen.ErrorCodes.ResourceNotFound || erro.Code() == "ENTITY_NOT_FOUND" {
    	d.SetId("")
    	d.MarkNewResource()
    	return nil
    }

• option 2: modify the GET project API, so that if returns {"code": "RESOURCE_NOT_FOUND_EXCEPTION"} when given project id doesn't exist
