WalkthroughThis change updates Matrix federation request validation. Query schemas now support AJV-coerced values, backfill versions use string arrays, and send-join requests use focused event validation. ChangesFederation validation
Estimated code review effort: 3 (Moderate) | ~20 minutes Mergeability Score: 🔵 Low · up to The federation send-join path may pass values that do not satisfy the SDK's required Matrix ID contract, risking rejection of otherwise valid join requests.

Learning: In RocketChat/Rocket.Chat OpenAPI migration PRs (e.g., PR `#39676` for users.register in apps/meteor/app/api/server/v1/users.ts), calls to `this.parseJsonQuery()` inside migrated handlers are intentionally preserved without adding a corresponding `query` AJV schema to the route options. Adding query-param schemas for the `fields`/`sort`/`query` parameters consumed by `parseJsonQuery()` is a separate cross-cutting concern shared by many endpoints (e.g., users.create, users.update, users.list) and is explicitly out of scope for individual endpoint migration PRs. Do not flag the absence of a `query` schema for `parseJsonQuery()` usage as a violation of OpenAPI/AJV contract during migration reviews.

Learning: In the EE audit migration, the deprecated Meteor DDP methods in `apps/meteor/ee/server/lib/audit/methods.ts` intentionally preserve their legacy behavior of validating only `startDate` and `endDate`; full request validation is provided by the replacement `/v1/audit.*` REST endpoints via AJV. The DDP methods are scheduled for removal in version 9.0.0, so hardening their payload validation is out of scope unless explicitly requested.

This is an established convention across all migrated endpoints (rooms.leave, rooms.favorite, rooms.delete, rooms.muteUser, rooms.unmuteUser). Do not flag this as a type mismatch during reviews of these migration PRs.

Learning: In Rocket.Chat's federation-matrix setup (ee/packages/federation-matrix/src/setup.ts and apps/meteor/ee/server/startup/federation.ts), configureFederationMatrixSettings does not need to be called before setupFederationMatrix. The SDK's init() establishes infrastructure (database, event handlers, APIs) first, and the configuration can be applied later via settings watchers before actual federation events are processed. The config only matters when events actually occur, at which point all infrastructure is already configured.

File: apps/meteor/ee/server/hooks/federation/index.ts:86-88
Timestamp: 2025-11-04T16:49:19.107Z
Learning: In Rocket.Chat's federation system (apps/meteor/ee/server/hooks/federation/), permission checks follow two distinct patterns: (1) User-initiated federation actions (creating rooms, adding users to federated rooms, joining from invites) should throw MeteorError to inform users they lack 'access-federation' permission. (2) Remote server-initiated federation events should silently skip/ignore when users lack permission. The beforeAddUserToRoom hook only executes for local user-initiated actions, so throwing an error there is correct. Remote federation events are handled separately by the federation Matrix package with silent skipping logic.

Learning: In RocketChat/Rocket.Chat, the `push.token` POST/DELETE endpoints in `apps/meteor/app/api/server/v1/push.ts` were already migrated to the chained router API pattern on `develop` prior to PR `#39625`. `cleanTokenResult` (which strips `authToken` and returns `PushTokenResult`) and `isPushTokenPOSTProps`/`isPushTokenDELETEProps` validators already exist on `develop`. PR `#39625` only migrates `push.get` and `push.info` to the chained pattern. Do not flag `cleanTokenResult` or `PushTokenResult` as newly introduced behavior-breaking changes when reviewing this PR.

Learning: In the RocketChat/Rocket.Chat repository, Meteor's bundler does not respect the `exports` keyword in `package.json` files.

Do not suggest adding `exports` map entries to packages consumed by Meteor (e.g., `packages/apps/package.json`) as a fix for deep imports.

Learning: In Rocket.Chat's federation invite handling (ee/packages/federation-matrix/src/FederationMatrix.ts), when a user rejects an invite via federationSDK.rejectInvite(), the subscription cleanup happens automatically through an event-driven flow: Matrix emits a leave event back, which is processed by handleLeave() in ee/packages/federation-matrix/src/events/member.ts, and that function calls Room.performUserRemoval() to clean up the subscription. No explicit cleanup is needed in the reject branch of handleInvite() because the leave event handler takes care of it.

Learning: In RocketChat/Rocket.Chat OpenAPI migration PRs, removing endpoint types and validators from `rocket.chat/rest-typings` (e.g., `UserRegisterParamsPOST`, `/v1/users.register` entry) is the *required* migration pattern per RocketChat/Rocket.Chat-Open-API#150 Rule 7 ("No More rest-typings or Manual Typings"). The endpoint type is re-exposed via a module augmentation `.d.ts` file in the consuming package (e.g., `packages/web-ui-registration/src/users-register.d.ts`). This is NOT a breaking change — the correct changeset bump for `rocket.chat/rest-typings` in this scenario is `minor`, not `major`. Do not flag this as a breaking change during OpenAPI migration reviews.

Use loose item schemas only when the underlying data source is inherently partial (for example, uploads with `content: null` or `findUsersOfRoom`'s fixed projection), not merely because a route supports an optional client `fields` projection.

This is an established convention across all migrated endpoints (rooms.leave, rooms.favorite, rooms.delete, rooms.muteUser, rooms.unmuteUser). Do not flag this as a type mismatch during reviews of these migration PRs.

Timestamp: 2026-03-15T14:31:28.969Z
Learning: In RocketChat/Rocket.Chat, the `UserCreateParamsPOST` type in `apps/meteor/app/api/server/v1/users.ts` (migrated from `packages/rest-typings/src/v1/users/UserCreateParamsPOST.ts`) intentionally has `fields: string` (non-optional) and `settings?: IUserSettings` without a corresponding AJV schema entry. This is a pre-existing divergence carried over verbatim from the original rest-typings source (PR `#39647`). Do not flag this type/schema misalignment during the OpenAPI migration review — it is tracked as a separate follow-up fix.

Timestamp: 2026-07-20T20:48:39.435Z
Learning: In the Meteor client, `apps/meteor/client/hooks/roomActions/useE2EERoomAction.ts` and `apps/meteor/client/views/room/E2EEWarningBanner/E2EEWarningBanner.tsx` both pass `getRoomTypeTranslation(room)?.toLowerCase()` to `apps/meteor/client/views/room/modals/E2EEModals/EnableE2EEModal.tsx`. The modal interpolates this value into `E2E_enable_encryption_description`; changes to room-type casing should update the shared modal contract and every caller together, rather than altering one entry point.

Timestamp: 2026-03-03T11:11:48.541Z
Learning: In apps/meteor/server/lib/moderation/reportMessage.ts, the reportMessage function validates that description is not empty or whitespace-only with `if (!description.trim())`. When migrating the chat.reportMessage endpoint to OpenAPI, adding minLength validation to the schema preserves this existing behavior.

Timestamp: 2026-03-20T13:52:29.575Z
Learning: In `apps/meteor/app/api/server/v1/stats.ts`, the `statistics.telemetry` POST endpoint intentionally has no `body` AJV schema in its route options. The proper request body shape (a `params` array of telemetry event objects) has not been formally defined yet, so body validation is deferred to a follow-up. Do not flag the missing body schema for this endpoint during OpenAPI migration reviews.

Timestamp: 2026-02-25T20:10:16.987Z
Learning: In the RocketChat/Rocket.Chat monorepo, packages/ddp-client and apps/meteor do not use TypeScript project references. Module augmentations in apps/meteor (e.g., declare module 'rocket.chat/rest-typings') are not visible when compiling packages/ddp-client in isolation, which is why legacy SDK methods that depend on OperationResult types for OpenAPI-migrated endpoints must remain commented out.

Learning: In Rocket.Chat typed REST response schemas, the pattern `allOf: [{ $ref: <Typia-generated entity schema> }, { properties: { success: { type: 'boolean', enum: [true] } }, required: ['success'] }]` is valid. Existing merged endpoints `server/api/v1/oauthapps.ts` for `IOAuthApps` and `server/api/v1/email-inbox.ts` for `IEmailInbox` use this composition and pass TEST_MODE response validation.
