Postgresql – Erro while upgrading my module in odoo to add a ir_cron

I’m getting this error when trying to ‘UPDATE’ my module through odoo interface to try to install the ir.cron

The above server error caused the following client error:

where should be my problem, I was expecting cron to add since I follow every step and added all fields and seems that he cannot find the eID, what could be wrong?

This is my models/iop_api.py that’s been already installed before handling cron.
