Socket.io : Could not load session for socket #.......

[billyshena]

Hello everyone. I've been working with sails 0.10.2 version and sometimes when I quit my browser and restart it to hit my app url , I get an error like this:

error: Could not load session for socket #F4O-lvWICcs6uQTYREOc
error: The socket's cookie could not be parsed into a sessionID.
error: Unless you're overriding the authorization function, make sure you pass in a valid sails.sid cookie
error: (or omit the cookie altogether to have a new session created and an encrypted cookie sent in the response header to your socket.io upgrade request)
error: TypeError: Cannot call method 'indexOf' of undefined

I've tried to debug but can't figure out what's wrong. Any kind of request to my Sails API launches this error and I have to make a refresh/F5 on my browser to make it work again.

Does anyone have an idea?

Ok the issue is a conflict of cookies => I've been using http://luisfarzati.github.io/angulartics/ to install Google Analytics with my angularjs application. For each request / call to my Sails js API, the cookie sent with the socket and the one sent by angulartics (for google analytics) somehow "come in conflict" and my SailsJS server prints this error.
I think Sails is getting the cookie sent by Google analytics first (which is not valid to Sails server) and prints out this error which stops the process.

Is there any workaround for this issue?
Regards

After some testing on my side, I could reproduce exactly the issue doing the following steps and the bug appears on one condition:

1. I close my browser + empty my cache
2. If I go on my http://localhost:8080 again, => socket ERROR appears => Could not load session for socket #....
3. If I refresh (F5) => everything works again

Conflict appears to be with Google analytics cookies and Sails socket cookie

[macedd]

Very weird behavior (if has to do with analytics)

Can a core dev give us any insights?

[macedd]

The problem is clearly addressed in this (thread)[http://stackoverflow.com/questions/21106983/unable-to-get-session-for-socket-in-sailsjs-after-restart].
Sockets can`t recreate the session, so a Jsonp request should be done before starting the io.

This feature could be implemented in sailsSocket with a failover.

[macedd]

To workaround the browser/socket/cookie problem just call the backend with an ajax call

# at console
$.get(window.io.sails.url)

But I have no idea of how to detect the problem and automate the workaround for socket-only apps

[billyshena]

thiagof: I'm using $sailsSocket and not ajax calls mhhh. However, this issue also appears with other websites cookie stored.

[macedd]

The ajax call is to restore your session with the backend, cause
socket calls do not make it.
But the workaround is for fixing development environment.
Production deploys can suffer from the problem someday...

Have you tried to enable session storage?

I'm getting the same thing. I overwrote my socket.js authorization to use my own logic. And according to the error message, that's one way to remove this issue, but that doesn't seem to be the case.

I'm wondering is there a way to turn off sessions in general (I'm using JWT). I've disabled the cookieParser middleware, but now want to also disable all sessions in generale.

[mikermcneil]

Sorry for the slow response guys.

@JetFault re: disabling session- you can do so by disabling the session hook. As of Sails 0.11, the sockets hook should fully support session-free usage.

@stenstrud @RobiFerentz @svnh @billyshena have you been able to reproduce this in Sails v0.11 w/ the new sockets hook?

[mackenrou]

Hi @mikermcneil
I updated to sails 0.11 disabling the session hook and fix this, but now socket don't connect on android browser and phonegap app as i explained here: #2874

[macedd]

Best solution to me were using a database session adapter
