Matchmaking error iOS

[ghostcubert]

I used sinum to redirect the backend to my ipa using the dylib injection and the backend works, the problem is matchmaking, both PC and Android work for me, iOS is the issue. It seems to be an issue inside matchmaker.js. It can also be a issue of how the matchmaker manages the token since on fiddler it shows the token and an error, maybe making token case insensitive?

Feel free to ask me for more info

Fix:

app.get("/*/api/game/v2/matchmakingservice/ticket/player/*", verifyToken, async (req, res) => {
    log.debug("GET /*/api/game/v2/matchmakingservice/ticket/player/* called");
    if (req.user.isServer == true) return res.status(403).end();
    if (req.user.matchmakingId == null) return res.status(400).end();

    const playerCustomKey = qs.parse(req.url.split("?")[1], { ignoreQueryPrefix: true })['player.option.customKey'];
    const bucketId = qs.parse(req.url.split("?")[1], { ignoreQueryPrefix: true })['bucketId'];
    
   
    const decodedBucketId = decodeURIComponent(bucketId);
    
    if (typeof decodedBucketId !== "string" || decodedBucketId.split(":").length !== 4) {
        console.log("[Debug] Invalid bucketId format:", decodedBucketId);
        return res.status(400).end();
    }
    
    const rawPlaylistId = decodedBucketId.split(":")[3];
    let playlistId = rawPlaylistId;
    
    if (!playlistId || playlistId.trim() === '') {
        console.log("[Debug] PlaylistId is empty or invalid");
        return error.createError("errors.com.epicgames.common.matchmaking.playlist.not_found", `Invalid playlist ID: ${playlistId}`, [], 1013, "invalid_playlist", 404, res);
    }
