User_ID not being set about universal-analytics

[mdenti]

This issue is really old, but I just butted my head on it so I'll write here the solution for anyone looking.

The docs are a bit misleading, but looking at the code here the uid needs to be passed in the options object to work. Alternatively you can use the persistent parameters.

I am also looking into this. It looks like the second param is only the cid which isn't the same as User-ID/uid.

@theoephraim did create #35 that addresses #34 for the same issue.

Thanks for the heads-up, just updated to docs.

Same problem still going on now
I am running on express and using this middleware function I wrote for all routes

const analyticsMiddleware = (req, res, next) => {
    const userId = req && req.user && req.user._id ? req.user._id : req.visitor.cid
    var visitor = ua(process.env.GOOGLE_ANAYTICS_TRACKING_ID, userId, { strictCidFormat: false});
    console.log(req.visitor.cid, req && req.user ? req.user._id : '', visitor);
    visitor.pageview(req.path).send();
    next();
}

Always has the incorrect cid , my custom userId from the database looks like this 5d52a69b062d1a150b345712
It is definitely not a UUID but isnt that strictCidFormat supposed to handle this case

If I call visitor.set('uid', '5d52a69b062d1a150b345712') as @mdenti mentioned I get an error saying invalid UUID format
Any ideas?

Update never mind,
I think this works

const analyticsMiddleware = (req, res, next) => {
    const userId = req && req.user && req.user._id ? req.user._id : req.visitor.cid
    req.visitor.set("uid", userId);
    req.visitor.pageview(req.path).send();
    next();
}
