From afbbd3fcde9c3c036a529d3f61640b93fc6482e8 Mon Sep 17 00:00:00 2001 From: Joel Wedemire Date: Tue, 28 Jul 2026 19:24:12 -0400 Subject: [PATCH] Reject non-scalar ids with 422 instead of 500 (#10) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `group_id: [14]` — a one-element array of a REAL group id — returned a 500. The reporter's analysis was right: `exists` given an array validates that EVERY element exists, which is multi-select behaviour, so an array of one valid id passed the rule and reached the controller. findOrFail() then returned a Collection and ->nextTicketNumber() on it fatalled. What hid it is that the rule looked like it was working: `['a','b']` was correctly rejected by `exists` with a clean 422. Only arrays made of valid ids got through. Adding `integer` ahead of `exists` fixes the reported field, but the hole was a property of `exists`, not of group_id — so every id on the endpoint had it. Fixed all nine sites across both controllers: store()'s group_id and priority_id, update()'s priority_id/project_id/group_id, and storeAgent/storeProject/storeEmailConnection's group_id (plus user_id, which fed straight into an access check). Tests pin the reported repro, the equivalent on priority_id, and both shapes that must keep behaving: a nonexistent id still 422s (so the exists check cannot be dropped later while the array tests still pass) and a normal scalar create still succeeds. Verified the array test FAILS with the rules reverted — it reproduces the 500 rather than merely passing.
