1) Contacts crash "c is null": contactRepository.Search declared `var contacts []models.Contact` so an empty result set returned a nil slice, which Go marshals as JSON null. The frontend's flatMap((p) => p.data) over null yields [null], and the page then accesses c.subscribed → throws. Initialize as make([]models.Contact, 0, limit+1) so the wire format is always []. Also defensive on the client: useSearchContacts + useCampaigns now coerce p.data ?? [] and drop nulls before returning. 2) Campaigns panic on any non-empty result: campaignRepository.Search allocated `make([]models.Campaign, 0, limit+1)` (length 0) then did `campaigns[i] = campaign`. That's an index-out-of-range on the first iteration. Switched to `append`. Anyone with at least one campaign would see a 500 / blank screen. 3) Websocket "Token expired": SocketTTL was 60s. The frontend reconnect backoff caps at 30s, so after a rejected handshake the next attempt could fire 30-60s later. Combined with rare back-pressure on /getaway the token was already past exp by the time the realtime saw it. Bumped to 10 min — short enough to keep the token low-impact, long enough to outlast the backoff schedule. 4) Websocket "Connection limit exceeded": Realtime.Connections only untracked on channel terminate, never on socket disconnect. Sockets that connected and disconnected without joining a channel leaked. Each reconnect loop bumped the counter until the per-user limit (10) was hit, after which every legitimate connect was rejected even after fixing #3. Fix: GenServer Process.monitor's the socket pid on track, and `:DOWN` handler calls do_untrack with the right (user_id, ip). 5) Phoenix protocol mismatch: Frontend appended vsn=2.0.0 to the WS URL, but sendRaw + joinChannel send the V1 object format. Realtime's Phoenix.Socket.V2.JSONSerializer crashed with a badmatch on the first phx_join, killing the socket right after connect. Switched to vsn=1.0.0 to match what the client actually emits.
