[OUTSYSTEMS].DBO.[OSSYS_USER_T20] with key 0 was not found

Sometimes when I open the app I see the following error: [OUTSYSTEMS].DBO.[OSSYS_USER_T20] with key 0 was not found. I can't reproduce it constantly and it happens very rarely, but I was wondering if anyone had faced this problem before. 

Hello Roman,

To see a detailed error, please go to service center and check where is that happening. After that just debug the app when you open it and check why it's happening like that. I would say that when you open the application you're doing something with the UserId (Update, Create) and it's passing that value as NullIdentifier() that'll trigger that error.

Hope it helps,

Best Regards,



It happen to me in the past using the function GetUserId() from a Timer.

Probably you are using this function in a asynchronous action (Timer or Process).




Luis, I think you might be right. I found one place where I call a server action which uses GetUserId() inside a process. However, I'm not positive why I am not getting this error constantly.
