I have a use case in my mobile application. I am trying to store the value of content-desc of an object called grand\_total, and print them in console -log ,. I have tried a lot of syntax, but keep hitting the wall

This is my code ( the one that I boxed in)… And katalon said that the object is null object.

This is the full error message :

This is the object properties of the object that I want to extract the “content-desc” from

Nb: I already tried checklist all the “Detect object by” , and also tried to checklist only the “content-desc”, but I still cant store and print the value of content-desc.

Any help will be greatlty appreciated. Thanks

Maybe try using `Mobile.getAttribute(grand_ttl, 'content-desc', 5)`.
