integer or string content inconsistency

Hi!

I'm having trouble trying to understand the following:

I have this:

If I try to use it in a flow and put the value in a variable, I have to initialize the variable as a string if I want to use it.

(If I try to use an integer variable here, I get an error telling me that the value is of String type

)

But then I try to use the following code:

empty(outputs('Subordinate')?['body/gs_metodoconocer'])

I get:

So, I'm confused. The variable must be a string if I don't want to get an error with the set. But the empty() function tells me that it's an integer and I can't use it.

Can someone please explain to me the behavior of this?

Hi @fsuarezoedt

You may try isInt function instead of empty function. The function 'isInt' return true if input is integer:

isInt(outputs('Subordinate')?['body/gs_metodoconocer'])

If this helps & solves your problem, please remember to give a 👍 and accept my solution as it will help others in the future.

It's not that my problem is the empty() function, or how to solve this logical step. I can also use an empty(string(output())). The question is:
WHY does the flow say Integer in one part and a String in another part?
