Aggregation module returns error

By chance, I got the following error:

Error in Aggregation(recipe = recipe, data = data) : 
  object 'res' not found

Because the recipe I was using for testing contain:

$Time_aggregation
$Time_aggregation$execute
[1] FALSE

Although the function Aggregation checks execute if (recipe$Analysis$Workflow$Time_aggregation$execute) { outside the condition there is the return(res).

I wonder if we need to reconsider the use of execute: yes/no in the recipe at least for this case. If it is allowed to change the option in the recipe T/F, means that I can call the module in the code, or, on the contrary, if there is no allowed option for execute in the recipe, the user should ensure if Aggregation is necessary in the code.

Cheers,
