Mayato (. Thank you, I'll have a look at this feature feature but I have already reached the maximum number of columns for a table ^^
To clarify my problem, 4 states are possible for my first query column :
Not run yet, returns nothing
Ran with error, returns nothing
Ran with success (200) but found nothing, returns nothing
Ran with success (200) and found something, returns an object
Vinit and Amit K. the problem with your solutions is the 3rd state... The column can be empty even if the request has been successful
