Greptile Overview

Greptile Summary

This PR makes the environments field optional in project templates by removing the .min(1) array requirement and changing from .optional() to .nullish() validation.

Key changes:

• Removes minimum array length requirement from ProjectTemplateEnvironmentsSchema
• Changes validation from .optional() to .nullish() in CREATE endpoint

Issues found:

• Missing early return in superRefine validation causes empty arrays to fail position validation checks
• Empty array [] bypasses default environment fallback in service layer, potentially creating SecretManager templates with zero environments

Confidence Score: 2/5

• This PR has logical errors that will cause validation failures for valid use cases
• The removal of .min(1) without adding an early return in superRefine creates a bug where empty arrays fail validation. Additionally, empty arrays bypass the default environments fallback, which may not be the intended behavior for SecretManager projects.
• backend/src/ee/routes/v1/project-template-router.ts requires fixes to handle empty arrays correctly

   logic: missing early return for empty arrays - will fail validation checks on empty array

   The superRefine runs uniqueness/position validation even when environments is empty ([]). Since you removed .min(1), users can now send empty arrays which will fail the position validation on line 86-92.
