Service Desk Template does not show any data on Dashboard page

[JacobH2]

Hi, I am new to use PowerApp. And now I am trying to use PowerApps template "Service Desk". But "All tickets" page does not show any data even ticket can be clicked and jump to another page which is ticket details. Data source file stored in OneDrive. 

Please help.

I like the UI.. that looks like a very clean power app, good job.

This forum is more related to Power Apps Portals questions, I will move this thread to the Power Apps forum where the experts will be able to help you better.

@OliverRodrigues - Thanks for moving this. Just for info (if you're interested in checking this out further), the service desk app is a built-in example app that we can create by using the 'start with a template' option.

@JacobH2 - Most likely, the app has encountered some condition where it isn't able to access the data source in OneDrive. With apps that we create from a template, it isn't simple to fix this type of problem because unlike a normal app, the data panel is hidden which prevents us from refreshing the data source.

If you haven't made too many changes to the app, the easiest fix may be to simply recreate the app.

Just to confirm that it is a data source problem, could you clarify the error message that appears against the red 'cross' icon in the designer?

Thanks for your comment. 

The following screenshot shows all error messages I am getting.
And once I click red cross button, red line shown on the top of page

If you created this app some time ago, an update to Power Apps may be the cause of this problem.

If you change the formula here to the following, does the error go away (note the ThisItem keyword)?

If(IsBlank(AssignedTo),"None",ThisItem.AssignedTo)
