After my migration from Odoo v13 to v16, after having uninstalled a custom module (website_signup_info) which have only a crontroller.py and a js-file: signup.js, and no other nodule has this one in its dependance:
__manifest__.py of the custom module website_signup_info:
# -*- coding: utf-8 -*i-
{
'name': ' website_signup_info : handle custom fields in signup ',
'version': '13.0.2.0.20',
'category': 'Website',
'summary': """handle custom fields in signup """,
'description': "handle custom fields in signup ",
'depends': ['website','auth_signup','auth_oauth','portal'],
'assets':
{
'web.assets_frontend': [
'/website_signup_info/static/src/js/signup.js',
],
},
'installable': True,
}
After uninstalling it and going to the website, i got this Error concerning unreachable ASSETS FRONTEND:

Any idea how to solve it ? Shall i remove the assets from database using SQL ?
We encountered a similar problem while uninstalling an Odoo module (almost the same error, just with web.assets_backend, and Odoo v15.0 instead of v16.0). The Odoo install may have been migrated to Odoo v15.0 from an older version previously, but we are not sure.
The solution was to first reinstall the module (using the Odoo CLI) to get rid of the error, manually enable debug mode, go into Settings -> Technical -> Assets, find the related asset, and delete it. Then uninstall the module as usual. You could probably also remove the asset using SQL without reinstalling the module.
My guess why this happens is that Odoo once handled these assets differently, and while migrating, this was not accounted for. When uninstalling the module, the asset is not removed, which then causes this error.
