Encryption setting and alert contract apps/meteor/server/settings/e2e.ts, packages/i18n/src/locales/en.i18n.json |
The forced-encryption setting now references an alert. English alerts describe its incompatibility with persistent video-conference chat. |
Runtime enforcement and validation apps/meteor/server/services/video-conference/service.ts, apps/meteor/tests/end-to-end/apps/video-conferences.ts |
Persistent chat is disabled when E2E encryption and forced private-room encryption are enabled. EE-only tests verify that behavior and confirm persistent chat remains enabled when E2E encryption is disabled. |
Estimated code review effort: 2 (Simple) | ~10 minutes
Merge Risk: 🔵 Low · up to d4b3e
The change prevents failed video-call creation when forced encryption conflicts with persistent chat, but the administrative enablement and warning conditions may not exactly match runtime gating, potentially leaving a supported configuration unnecessarily unavailable; owner follow-up is recommended.

Starting a video call failed when both "Force end-to-end encryption on private rooms" and video conference persistent chat were enabled. Persistent chat creates its discussion with `encrypted: false`, so the forced-encryption policy rejected the room creation with `error-encrypted-private-rooms-enforced`. Because `maybeCreateDiscussion` runs before the call URL, start message and notifications, the throw aborted the whole call and left a conference record with no URL, no start message and no notifications behind. Direct calls stayed in CALLING (the 40s auto-cancel timer is registered after the discussion step, so it never ran) and group calls stayed in STARTED. Persistent chat discussions are unencrypted, so the two features are incompatible. `isPersistentChatEnabled` already gathers every setting that must be active for persistent chat, so the encryption policy is now checked there as well: while it is enforced, persistent chat is treated as disabled and no discussion is attempted, which keeps the call start path untouched. The policy is also a requirement of the persistent chat setting itself, so it can no longer be enabled while encryption is enforced. Also adds a warning to the "Force end-to-end encryption on private rooms" setting stating it is not compatible with video conference persistent chat.

Learning: In this repository (RocketChat/Rocket.Chat), Biome lint rules are not used even if a biome.json exists. When reviewing TypeScript files (e.g., packages/ui-voip/src/providers/useMediaSession.ts), ensure lint suggestions do not reference Biome-specific rules. Rely on general ESLint/TypeScript lint rules and project conventions instead.

Learning: In the Rocket.Chat repository, do not reference Biome lint rules in code review feedback. Biome is not used even if biome.json exists; only reference Biome rules if there is explicit, project-wide usage documented. For TypeScript files, review lint implications without Biome guidance unless the project enables Biome rules.

release-8.8.0, where the feature landed. Fixes a regression introduced by #41095: starting a video call from a direct message or private room fails when Force end-to-end encryption on private rooms and video conference persistent chat are both enabled.Root cause
Persistent chat creates its discussion with
encrypted: falsehardcoded (service.tscreateDiscussionForConference), andgetDiscussionTypereturns'p'for a private/DM parent. The forced-encryption policy added in #41095 therefore rejects the room creation witherror-encrypted-private-rooms-enforced.The damage comes from where that throw happens. In both
startDirectandstartGroup,maybeCreateDiscussionruns before the rest of the start sequence and was not guarded, so the throw aborted everything after it — while theVideoConferencerecord had already been inserted:VideoConferenceModel.createDirect/createGroupmaybeCreateDiscussionsetUrlByIdcreateMessage/setMessageByIdCALLINGsendPushNotification/ringbroadcastThat matches the report exactly, including direct calls stuck in
CALLINGand group calls inSTARTED. The error is then swallowed by the endpoint'scatch, which returnsdiagnoseProvider(...)— and since the provider is healthy that resolves toundefined, so the client only shows the genericerror-videoconf-unexpected.The fix
Persistent chat discussions are unencrypted, so the two features are simply incompatible. Rather than letting the room creation fail and recovering from it, persistent chat is now treated as disabled while the policy is on, so the discussion is never attempted and the call start path is untouched.
isPersistentChatEnabled()already gathers every setting that must be active for persistent chat, so the policy was added there as one more condition — inactive instead of active:No setting is written based on another —
VideoConf_Enable_Persistent_Chatkeeps whatever value the admin gave it, and both settings are simply validated together where it matters. So even with persistent chat on, enforcing encryption makes the code treat it as off.The policy is also a requirement of the persistent chat setting itself (
enableQuery), so it can no longer be turned on while encryption is enforced.E2E_Enableis checked alongside the policy because the policy only takes effect when E2EE is on — that mirrorsbeforeCreateRoom.tsand the create-room modals, which validate the same pair.Files

Issue(s)
CORE-2621
Regression from #41095, which is part of 8.8.0.
Steps to test or reproduce
E2E_Enable,E2E_Force_Encryption_For_Private_Rooms,Discussion_enabledandVideoConf_Enable_Persistent_Chat.Before: call creation fails, server throws
error-encrypted-private-rooms-enforced, client showserror-videoconf-unexpected, and an unusable conference record is left behind (no URL, no discussion, no start message, no notifications; direct calls stuck inCALLING, private-room calls inSTARTED).After: the call starts normally and no persistent chat discussion is created. In Admin → Settings → Video Conference, Enable persistent chat is also greyed out while the policy is on.
Also check Admin → Settings → End-to-End Encryption: the Force end-to-end encryption on private rooms setting now shows the incompatibility warning.
Further comments
Gating the feature is preferable to catching the failure: nothing is attempted, so there is no error to recover from and no partially built conference record to reason about.
Note this disables persistent chat for every call while the policy is on, including calls in public channels where the discussion would not have been rejected. That is intentional — it keeps the rule predictable for admins and matches what the setting warning states.
Worth noting separately (not changed here): the start sequence inserts the conference record before it can guarantee a usable call, so any failure between those points still leaves an unusable record with direct calls stuck in
CALLING. That is pre-existing and no longer reachable through this path, but it is the underlying fragility.Worth noting separately (not changed here):
video-conference.startdiscards the real error in itscatchand returnsdiagnoseProvider(...), which is why this failure was invisible from the client. Making that endpoint surface the underlying error would help diagnose similar issues, but it is out of scope for this regression fix.Validated locally against
release-8.8.0:tsc --noEmitreports the exact same 49 errors with and without this change (all pre-existing on that branch, in unrelated client sidebar components), so it introduces none. ESLint reports 0 errors on all changed files — the 5 remaining warnings inservice.tsare pre-existing — and the i18n sort/validity check passes.🤖 Generated with Claude Code
