Module: BACKEND / Express API & Data Access
Coverage Requirement: Requires minimum 80% coverage on new logic
Test files: - BACKEND/tests/**/*.test.js
Description
Fix a critical \ReferenceError\ in the \getRelatedProducts\ controller. At line 407 in \product.controller.js, the code attempts to use \ argetTags.has(), but the variable was initialized earlier at line 376 as \ argetTagsSet. This typo causes an immediate 500 Internal Server Error whenever the related products endpoint is accessed.
Why this is critical
Central implementation hub — The backend orchestrates all data integrity, authentication, and payment workflows. A nil-pointer, uncaught promise rejection, or zero-value bug in any API layer can silently disable features or crash the server cluster.
Blast radius and impact if broken:
Frontend / UI: Frontend clients will receive 500s when rendering product detail pages or any view that fetches related products.
Backend / API: Direct impact. The \getRelatedProducts\ endpoint will consistently panic and throw an unhandled exception.
State / Data Integrity: No direct data corruption, but a total loss of the recommendation feature.
Files involved
BACKEND/controllers/product.controller.js
Suggested approach
Initial Assessment: Review the current implementation within the targeted files. Identify zero-value defaults and interface compliance requirements.
Implementation: Rename \ argetTags\ to \ argetTagsSet\ at line 407 in \BACKEND/controllers/product.controller.js. Ensure there is no indirection, missing validation layers, or defensive copying failures.
Testing Requirements: Write strict unit/integration tests covering the new execution paths (specifically testing the \getRelatedProducts\ endpoint). Ensure zero-value, nil-pointer, and boundary scenarios are gracefully handled or documented.
Validation: Run the CI pipeline locally (npm run test, npm run lint) to ensure code quality standards and coverage thresholds are met before submitting the Pull Request.
