Hi,
Are you using Odoo v11?  In the V11 there are some changes in the report section,  report module has been removed along with report object. For this reason, you are facing this error.

In v11, you can call the report using report_action [1]  as follow:

self.env.ref('custom_report_name').report_action(self, data=data)
