Hello everyone,

I have created an app and want to import it in another database (new Odoo Studio). I've managed to Export it by clicking Customization --> Export. On the new database, I clicked Cusomization --> Import but get the error as below:

RPC_ERROR
Odoo Server Error
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

The above server error caused the following client error:

Imported customization: saas~16.2+e

I don't know where I have done wrong? Please help
