a!queryRecordType yesterday worked but not today

Your help will be very appreciated.

In DESIGN mode of Designer, today the Interface shows:

 Could not display interface. Please check definition and inputs. Interface Definition: Expression evaluation error [evaluation ID = INH9G] : Cannot compare incompatible operands of type Lista de nulos and type Número (entero).

(I don't know why sometimes is full in English and now partially in Spanish. I have always worked in English.)

Yesterday I made several combinations using and not using rule expressions, declaring local variales that didn't show in the right pane  and putting the filter of idType = 1 just below the recordType: parameter and the null and not null owner field filters in their corresponding measure. Also, I tried moving the idType = 1 filter to each filter parameter of measure. The objective is to count  the owned assets (not null) and to count the available assets to assign (null) for workstations (idType = 1). owner is User and idType is Integer.

Yesterday the query calculated both aliases but today show the message.

                 operator: "=",
                 value: 1
              )
           }
      )
   }
),
pagingInfo: a!pagingInfo(1, 500)

).data

Do you know why this behavior and how can I fix it?
