…rofullstack#147) When title or description fields are provided as non-string values (e.g., numbers, booleans, objects), calling .trim() would crash with a TypeError, resulting in a 500 error. Now returns 400 with a clear error message instead. Fixes profullstack#147
Greptile SummaryThis PR fixes a
Confidence Score: 3/5The route fix itself is correct and safe, but the test file for the new validation helper is broken — the tests will not run as written. The core route change in route.ts is correct and the regression tests in route-regression.test.ts cover it well. The validation.test.ts additions are broken — validateApplyNote is never imported, so those tests all fail with a ReferenceError. The helper itself is also dead code in production since apply/route.ts never uses it. src/lib/affiliates/validation.test.ts needs the missing import fixed before the new tests can run; src/app/api/affiliates/offers/[id]/apply/route.ts and src/lib/affiliates/validation.ts should be reconciled so the helper is actually used.

validateApplyNote
The test suite calls validateApplyNote(...) throughout, but the import at line 2 only brings in validateOfferInput, stripHtmlTags, and isValidUrl. Every test in the validateApplyNote (#145) describe block will throw a ReferenceError: validateApplyNote is not defined at runtime, meaning none of the claimed "passing" regression tests for #145 actually run.

validateApplyNote is unused; inline logic duplicates it
This PR adds validateApplyNote to validation.ts specifically to centralise note validation, yet apply/route.ts never imports it and reimplements the same logic inline. The new function is dead code. Replacing lines 75–88 with a call to validateApplyNote would remove the duplication and actually exercise the tested utility.

Fix for #147 — affiliate offer edits crash on non-string title or description
Problem
The PATCH /api/affiliates/offers/[id] endpoint calls .trim() on title and description without checking their type. If a non-string value is sent (e.g. title: 123 or description: true), .trim() throws a TypeError, resulting in an unhandled 500 error.
Solution
Added type guards before calling .trim():
Tests
8 regression tests added covering:
