I have created a transient model (wizard). in the playground stage it's all good but when I merge my changes in the production stage. this is the error. Can anybody help? 
Odoo is the world's easiest all-in-one management software.
It includes hundreds of business apps:
- CRM
- e-Commerce
- 会計
- 在庫
- PoS
- Project
- MRP
Can you please try to change the name of your current wizard?
Thanks & Regards,
Sunny Sheth
