Nested Gallery Giving a Runtime Error on App Start

(0) ShareShare

Posted on by 91

Hi Everyone, I have an app with three screens with the same gallery and all three screens give me a runtime error on app start. When we go into those screens, the error goes away. I have attached the error message from studio.

 

Essentially we have a gallery inside a gallery. The parent gallery is a flexible gallery that only contains appointment dates from a dataverse table and the nested gallery contains appointment slot data from those specific dates. We are not sure why this error messages is coming up every time we run the app. Has anyone had any experience with this? If so, any kind of help will be very appreciated. Thank you.

    I resolved the issue by adding !isBlank() conditions in my if statements for all the fields that are showing as null in the run time error.
