harden help center validation and fix automation previous_* values - #504
Merged
Conversation
Help center saves now reject what they used to silently drop. name, page_title and meta_description get length caps on the backend, and the zod schema mirrors them so the error shows before the request goes out. A theme that cannot be read returns an error instead of collapsing to an empty theme and wiping the saved appearance. Protocol-relative URLs like //evil.com are discarded, nav links with no label are dropped, and an unknown social platform falls back to website. An announcement link with no text is a form error now, because save drops the whole banner in that case. Added tests for theme normalization. Request validators return envelope errors instead of writing the response themselves, so the handler decides the status code. They also trim names and emails before checking them. Same change in the chat, users and help center handlers. Automation previous_* filters no longer see post-change values. The by-ID path passes nil, so a rule filtering on previous_status will not match instead of comparing a value against itself. The incoming message path drops its fallback for the same reason. Team assignment also stopped firing its automation event when an unrelated step failed, for example fetching the team or applying its SLA. Those errors log and carry on now. Small UI fixes: slug generation strips accents, a language already picked in one row is hidden in the others, and a failed submit scrolls the first error into view without jumping the page.

Array.from(value).length, matching the backend limits instead of JavaScript

that the help center was left unchanged, leaving only the unreadable

- Around line 856-859: Update the team-change branch in the conversation
assignment flow to capture the error returned by RemoveConversationAssignee and
log it using the existing error-logging convention, while preserving the
non-critical continuation behavior.
- Around line 860-875: Update the team-assignment flow around GetConversation
and EvaluateConversationUpdateRules so automation is always evaluated: use
updatedConversation when the refresh succeeds, otherwise fall back to the
pre-change conversation value and ensure its AssignedTeamID reflects the new
team ID using the field’s existing type. Keep SLA application conditional on
successful refresh while emitting EventConversationTeamAssigned in both paths.

1539-1545: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick winReuse the cached agent lookup instead of
GetAgent.
resolveNotifyRecipientsalready loads every recipient throughm.userStore.GetAgentCachedOrLoadat Line 1615. This loop then loads the same agents again throughm.userStore.GetAgent, which is an uncached lookup per recipient. For a rule that notifies a large team, this adds up toamodels.MaxNotifyRecipientsextra queries per event.
GetAgentCachedOrLoadis part of theuserStoreinterface at Line 166, so the switch is local.♻️ Proposed change to use the cached lookup
for _, id := range userIDs { - recipient, err := m.userStore.GetAgent(id, "") + recipient, err := m.userStore.GetAgentCachedOrLoad(id) if err != nil { m.lo.Error("notify: error fetching agent for email", "user_id", id, "error", err) continue }Confirm that

NotifyMention and notifyAutomation carried the same ~55-line loop that fetches each recipient and builds an index-aligned email list. Extract it into buildRecipientEmails with a render callback so the alignment invariant lives in one place. Agent lookups now go through the TTL cache, and a failed lookup no longer drops the in-app notification. Also from the review: extract applyTeamSLA to flatten the error ladder on team change, trim values before the help center frontend length checks so trailing spaces don't fail a value the backend would accept, and drop two stale comments.
