The uuid matcher used the character class [0-9a-zA-F], so any letter a-z (e.g. "zzzzzzzz-zzzz-zzzz-zzzz-zzzzzzzzzzzz") passed as a UUID. Use [0-9a-fA-F] so only hexadecimal digits are accepted.

Problem
router.matchers.uuid()accepts any lowercase letter, not justa-f, soGET /posts/gggggggg-gggg-gggg-gggg-ggggggggggggreaches a route guarded with.where('id', router.matchers.uuid()). The character class insrc/router/matchers.tsis[0-9a-zA-F]; #50 asked for[0-9A-Fa-f]and #53 landeda-zfor the lowercase half.Fix
Use
[0-9a-fA-F]. Valid UUIDs in either case still match.Testing
