Hello, 

I'm trying to implement the code explained in this page

https://www.odoo.com/fr_FR/forum/aide-1/question/how-to-programatically-run-a-report-and-add-it-as-an-attachment-36449

But i get this error:

I think this is a simple error, but I'm a beginner and i can't find where is the problem

Thank you for your help
