Hello Francisco,

Hope you're doing well.

As you can see, your If condition is depending on GetStockByProductId Aggregate:

But you are running this Aggregate after the If condition:

So by the time the if condition is executed, the aggregate doesn't have any results. Therefore, it's always empty.

You should put your Aggregate before the If condition:

And are you sure it is always going for False branch? As I can see it is always going to True.

Nevertheless, this one should be very easy to find using debug :)

Hope that this helps you!

Kind regards,
