Thanks a lot Stefan! You were right, just by initializing the local variable in the line two the error disappears. Now it works properly

Sure. That is because now, you put a NULL value into a list and try to count the items in that list. That will again evaluate to "1" in case the local variable is NULL.

I repeat my suggestion: "I suggest to initialise it using "{}"."

You need to do that in line 2 of your code in the initial post.

Thanks Stefan! I have changed the expression to count({}) but it´s happening the same

That's simple. count() includes NULL values. In the initial state, your local variable in line 2 holds a single NULL value. I suggest to initialise it using "{}". This makes it an empty list. Then count({}) equals zero.
