I would like to run a Python Code every time a new user who was invited to the portal creates a password and connects for the first time. 

Any idea why this action is not triggering? I have tried while triggering the State field (which should be the one updating) but also tried with Status field, I have tried with or without domain filters, I have tried to execute a code or create a new record but nothing is working, nothing is being triggered by the update of the User. 

Can you take a look, what am I missing? 

Thanks
