QuickBlox iOS failed with error code 422 - ios

Question

I am using QuickBlox iOS SDK (version 2.9.2) and got a failure with error code 422 when calling
[QBRequest createObject:qbcoCustomObject successBlock:^(QBResponse *response, QBCOCustomObject *object) {
} errorBlock:^(QBResponse *response) {
}];
It happens OCCASIONALLY and does not resume until I logout and login QuickBlox again.
The error message is as follows:
2017-04-24 06:18:45.855557 App[8720:4958563] [QBCore] Response error: Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: client error (422)" UserInfo={com.alamofire.serialization.response.error.response=<NSHTTPURLResponse: 0x17422ed40> { URL: https://api.quickblox.com/data/MyCircleComments.json } { status code: 422, headers {

);
};
}
Due to the fact that it resumes only after I logout and login again, I was thinking that it may be related to session expiry. I added login method at the app's didFinishLaunching and didBecomeActive so that the app will automatically re-login to make sure the login session be valid. The login method I use is
[QBRequest logInWithUserLogin:sUsername password:sPassword successBlock:^(QBResponse *response, QBUUser *user) {
} errorBlock:^(QBResponse *response) {
}];
and by setting breakpoints I am sure each time the auto relogin did succeed.
However, app's auto-relogin does not work. The failure still happens occasionally and the only way out is logout and login manually.
I googled this issue and found a bunch of topic but none seems to meet my problem. (One post suggests that the time of device may not be synchronized but actually my iPhone is using the network time.)
Can anyone give me a hint why it fails and a solution is highly appreciated. Thanks in advance.

Answer 1

One of the best answer for above issue:-
**"Bad timestamp means that you send invalid timestamp value on session creation, which is based on your phone time. Your device time shouldn't differ from server more than 2 hours.
We suggest you synchronize time on your devices with NTP service or just set tick 2 checkboxes in Settings in your device: Automatic date & time and Automatic time zone.
Hope this help"**
Ref :- https://github.com/QuickBlox/quickblox-ios-sdk/issues/452
From setting of the device set timezone automatic on.
Hope this will help you.

Answer 2

Try to get Quickblox session token
[[[QBSession currentSession] sessionDetails] token];
And check session type via REST API
//QuickBlox Documentation
curl -X GET \
-H "QuickBlox-REST-API-Version: 0.1.0" \
-H "QB-Token: 8b75a6c7191285499d890a81df4ee7fe49bc732a" \
https://api.quickblox.com/session.json
If field "user_id" of your token will be equal to 0 this mean that you have "application-token" type, and you cannot create or update items on QBlox, after login with session token "upgrades" to "user-token"
I have similar issue, and i made extra check, if token-type is application, then you need login with same user again (recursively call login method if you can), i know that its a workaround, but we cant dig deeper because all locked in Quickblox.framework
