16.0 [fs_storage] cannot add a storage backend through the UI

[vdl-dsi-architecture]

Module

fs_storage

Describe the bug

When adding a storage backend with any protocol, you get an error.

To Reproduce

Affected versions: 16.0

Steps to reproduce the behavior:

1. go to the storage backend list
2. add a new one
3. select any protocol (in our case, s3, but we couldn't get the same error with others)

Expected behavior
It works

Additional context
I can see this bug open on odoo itself odoo/odoo#117559

Does that mean that fs_storage hasn't worked since 2023? I'm really confused. The setup documentation is very sparse (as can be seen by the "How does this works" issues in the repo).
