Bug in Build an Application Step 5

Certified Associate Developer

Hi everyone, I'm using the latest Appian Community Enviroment, but I can't finish the Step 5.  In the Edit List part I use this Expression:

if(a!isNullOrEmpty( fv!row[recordType!W#SA Vehicle.fields.image] ), a!EXAMPLE_DOCUMENT_IMAGE(), fv!row[recordType!W#SA Vehicle.fields.image] )

And I get the following error: 

Expression evaluation error at function a!gridField_23r3 [line 51]: A grid component [label="null"] has an invalid value for "columns". A grid column [label="Image"] has encountered an error. Expression evaluation error at function a!imageField [line 52]: User Does Not Have Rights to Perform this Operation

I don't have access to the database or any vehicle data to manage the user permissions.

Thanks!
