Tengo instalado Tryton 2.8 y al instalar el módulo sale_shop 3.0 me arroja el siguiente error:

En la consola del servidor al instalar el módulo sale_shop desde el wizard:

Como referencia les comento que este mismo módulo lo instalé en otro servidor de prueba y no me marcó errores.
Alguien puede decirme como corregirlo?

En la bd de datos tiens ya pedidos creados. No partes de una base de
datos nueva. Deberás hacer un SQL a mano para solucionar que los
pedidos de venta van relacionados con tiendas.

También importante configurar los usuarios con las tiendas que
permites la venta. Para hacer una venta, asegurate que en sus
preferencias dispongan las tiendas que van a vender y la tienda que
está vendiendo este momento.
