Bug in Build an Application Step 5

Question

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!

Hi Naina Kumari , 
 If you are using the Us.appian.community site. definitely, you'll get this because some of the images are present in the appian are not accessible . Still they don't permit us to use them, we cannot change the permissions of the images as we are just basic users in the community site.

Can you write the entire code, where you are using the expression, to get more clarity? 
 Although it seems to be a security issue for the document. Try checking the folder, KC and document security.

 As Varun Mentioned, you don't have permission. I would suggest you to remove the image constant, add new image and create constant and use
