Powerapps Service Availability/Performance Issues!! - Frowny face, Datasource not found

[Cybersurfer411]

11/13:

We are constantly facing app crashes and our IT teams are up most of the nights over the last week multiple times with Apps coming up with a "sad face" every few hours over the last one week!

 https://powerusers.microsoft.com/t5/General-Discussion/Powerapps-Errors-Frowny-face-Datasource-not-f...

 Is there any solution in site for these performance issues? or should we recommend our clients not consider this solution at all?!

 We cannot have this maintenance nightmares and constant reboots/refreshes of the App.

 Thanks.

Original post:

Hello all,

We developed a "Whiteboard" style display App that is supposed to stay ON on a overhead display & refresh every 5 mins (Gallery refresh set to x5 mins) and we wrote an automated system level scheduled task to reboot the device and auto-login to powerapps every 4 hours to keep the session active. It is currently running on Chrome. We use a on-prem datasource to connect the App using a gateway to a SQL Server. There are less than 5 active users using the App at any given time.

The system/bowser running the App is dedicated and has nothing else running on it.

 Do we know how often the Browser needs to refresh or what may be causing the below issues?

1. We keep getting a Black screen/frowny face/sad face error once in a while for no reason. (Attached pic)

2. When we open the App to click "edit items" in Gallery to update items, we keep getting "Datasource Not Found" intermittently. There is always a need to let it "sit" (loading) for a while before we can click the ">" arrow to edit the item. I also added a "loading" icon which disappears After the full App's "OnStart" routine is completed and only then edit items but we still face the same issue. We have had to Refresh the App multiple times to be able to hit the arrow to go to next update screen to work!

 

We've tried all kinds of options inlcuding using ClearCollect & Refresh(DS) to refresh, logon/off the system to reload browser/device but none of it seems to help and these intermittent issues are causing the App useless as the "Display Board".

Is anyone else facing a similar issue? Thanks!

@Cybersurfer411, 

As a general update, we have a fix set to be released in an upcoming release regarding the controls being cut off, but we are continuing to investigate the "No datasource provided" issue.

Are you still experience this? 

If so, can you please provide another sesson ID, as the old ones have since expired.

This would really help in our investigation to better our service.

Thanks

Hi @Cybersurfer411,

Looking at the post history, it looks like Cherie already asked you to ensure that the delay loading feature gate was enabled. Can you try disabling this to see if this mitigates your data source not found issues?

Thanks,

Michael

@Michael

Today, I disabled the delayed load option on one of the Apps. We will let you know if that fixed anything because we had the same "Datasource" issue as recently as yesterday. 

I will keep you posted.

Thank you for the follow up.
