Python Peewee AttributeError - When I consult with more than one join

I am trying to make a query with ORM Peewee with a connection to an existing database . Specifically I need to relate three tables with joins but I get the following error:

(work) C: \ Users \ eguzman \ Documents \ python-work \ asterisk-insert-reminder> python script.py Traceback (most recent call last): File "script.py", line 41, in row.ageagendas.CODIGO, row.ageagendas.PER_ID, row.stkpersonas.DOCUMENTO)) AttributeError : 'AgeCitas' object has no attribute 'stkpersonas'

Probably the problem is related to the declaration of the fields in the model, but as I am not an expert in Peewee I do not detect the problem, I leave the code, thanks ...

The code: script.py

import peewee as pw
from classes.model import MySqlDbModel, AgeCitas, AgeAgendas, StkPersonas


class SelectCitasToRemind(MySqlDbModel):

    @staticmethod
    def selectCitasToRemind():
        cit = AgeCitas.alias()
        age = AgeAgendas.alias()
        per = StkPersonas.alias()
        query = (cit.select(
            cit.CIT_ID, cit.AGE_ID, cit.FECHAHORA,
            age.AGE_ID, age.CODIGO, age.CEN_ID, age.PER_ID,
            per.PER_ID, per.DOCUMENTO, per.NOMBRE)
            .join(age, pw.JOIN.LEFT_OUTER, on=(cit.AGE_ID == age.AGE_ID))
            .join(per, pw.JOIN.LEFT_OUTER, on=(age.PER_ID == per.PER_ID))
            .where((cit.CIT_ID.is_null(False))
                   & (cit.PAC_ID.is_null(False))
                   )
            .limit(10)
        )
        return query


 query = SelectCitasToRemind.selectCitasToRemind()

 for row in query:
     print("{} | {} | {} | {} | {} | {}".format(
        row.CIT_ID, row.AGE_ID, row.FECHAHORA,
        row.ageagendas.CODIGO, row.ageagendas.PER_ID, row.stkpersonas.DOCUMENTO))
