Question

Error after application is idle for a long time


After my program is running for about 20 minutes the application crashes with the following error:

System.Exception: Access token corrupted

at RingCentral.Subscription.SubscriptionServiceImplementation.Renew()

at RingCentral.Subscription.SubscriptionServiceImplementation.OnTimedExpired(Object source)

at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx)

at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx)

at System.Threading.TimerQueueTimer.CallCallback()

at System.Threading.TimerQueueTimer.Fire()

at System.Threading.TimerQueue.FireNextTimers()



This is my code:

Dim subscription = New SubscriptionServiceImplementation With {._platform = ringCentral}

subscription.AddEvent("/restapi/v1.0/account/~/extension/~/presence?detailedTelephonyState=true")

Dim responsePub = subscription.Subscribe(AddressOf ActionOnUser, AddressOf ActionOnConnect, AddressOf ActionOnError)

Hi Eziel,

It looks like you are using the C# SDK. If so, what version are you using? We recently fixed an issue that sounds like this with the latest release, 0.1.21, which is on Nuget and GtiHub.


If you are running into this issue with version 0.1.21 of the C# SDK, please create an issue for the C# SDK here:


Thanks!

Yes I'm using RingCentralSDK.0.1.21 got from nuGet.

Thanks for the reply, I created an issue on gitHub https://github.com/ringcentral/ringcentral-csharp/issues/24

Thanks for creating the issue in Github. :)

Today the UserCallback stopped firing on presence changes. [the connect event does fire and says "Connected".

I didn't change any code since yesterday, not sure why it won't work anymore.


(I wrote the same comment on gitHub too)

Eziel has indicated that this issue only occurs in production and not in sandbox here:

Since this sounds like an API issue and not a SDK issue, we'll need our DevRel team to work with you on this who I've informed of this thread and will follow-up. Please provide additional information here or open a support case.
