From 0c24a4345f61f27a4e02c4469621e6f923ba2e89 Mon Sep 17 00:00:00 2001 From: Backend Agent Date: Sun, 12 Apr 2026 14:23:32 +0000 Subject: [PATCH] fix: add /filters endpoint to resolve 500 error on GET /supplements/filters Added GET /api/v1/supplements/filters returning distinct categories, brands, and countries. Placed before /{id} mapping so Spring MVC matches the exact path first. Previously "filters" was parsed as UUID, causing IllegalArgumentException -> 500.
