Description

Plex's import already refreshes already-known users' avatar/username on every click and hides them from the picker. Jellyfin/Emby import only created new users and showed everyone regardless of import status, this change brings parity between both components. It also fixes a bug found while mirroring Plex's matching logic: a plexIdstring/int mismatch. To align the Plex and Jellyfin implementations, user filtering was moved server side instead of client side for the Jellyfin path.

AI Disclosure: No AI was used to make these changes.

How Has This Been Tested?

I tested these changes by running existing and new unit tests ensuring that they passed. I also ran test imports against local Jellyfin and Plex instances with cases where not all users were imported previously but also when all users had been previously imported and the call was syncing only,

📝 Walkthrough

Walkthrough

The PR updates Jellyfin and Plex import responses, refreshes existing Jellyfin users, filters imported users from selection results, supports sync-only imports, adds an avatar timeout, and adds integration coverage.

Changes

User import synchronization

Layer / File(s) Summary
Import API contracts and processing
seerr-api.yml, server/routes/settings/index.ts, server/routes/user/index.ts, server/routes/avatarproxy.ts
Import responses now return created users and refreshed-user counts. Jellyfin imports refresh existing users, support optional request bodies, and create only selected new users. Jellyfin listings exclude imported accounts. Avatar metadata requests use a five-second timeout.
Jellyfin import interface
src/components/UserList/JellyfinImportModal.tsx, src/components/UserList/index.tsx, src/i18n/locale/en.json
The modal supports import and sync-only flows, consumes the new response shape, lists returned users, removes the children query path, and displays updated status messages.
Import route integration coverage
server/routes/user/index.test.ts
Integration tests cover Jellyfin creation, refresh, identifier handling, response counts, omitted bodies, Emby behavior, and Plex matching and email normalization.

Merge Risk: 🔵 Low · up to 619c3

Some existing Jellyfin users may reappear in the import picker and be offered for redundant import attempts, so the ID comparison should be aligned before merge.

758-792: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

The existing-user lookup in the Jellyfin import handler compares a normalized incoming ID against the raw, un-normalized jellyfinUserId column. Local users created through Jellyfin/Emby SSO login (server/routes/auth.ts) store account.User.Id unnormalized, so if that stored ID differs in dash format from the ID returned by getUsers(), this lookup misses the existing record and the import path creates a duplicate User row for the same account instead of refreshing it. Normalize the stored ID (or fetch and compare via normalizeJellyfinGuid on both sides) before deciding whether a user already exists.

477-501: 🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Normalize stored Jellyfin IDs before filtering existing users

If account.User.Id uses a dashed GUID, the login and account-linking paths store it without normalization, while /jellyfin/users compares normalized IDs with the raw database value. The existing user is then returned as unimported and can be selected for import again. The import route refreshes the matching user instead of creating a duplicate, so this is a picker correctness issue. Normalize the stored value in the lookup or use the same canonical comparison as the import route.
