_ in both ApiBasketMiddleWare and translations?

Hello, When I add the "oscarapi.middleware.ApiBasketMiddleWare", I get the error:


System check identified no issues (0 silenced).

ImportError: cannot import name 'ugettext' from 'django.utils.translation' (django-oscar-api/.venv/lib/python3.10/site-packages/django/utils/translation/__init__.py)

I'm using the sandbox with included settings.py:

from django.utils.translation import gettext_lazy as _
...
USE_I18N = True
LANGUAGE_CODE = "en-us"
LANGUAGES = (
    ("en-us", _("English")),
    ("fr", _("French")),
)

As soon as I comment the middleware, it works again.

For now, I replace _ with i_: from django.utils.translation import gettext_lazy as i_ and subsequent calls in languages ("en-us", i_("English")),.... It seems to work.

I'd love to know if there's a better fix.

Additionally, may I ask for an example of "fill your basket with the API and use plain Oscar views for checkout" as stated in the doc? https://django-oscar-api.readthedocs.io/en/stable/topics/outofthebox.html?highlight=basket#middleware-and-mixed-usage In my case, the API is called by a browser on a different port.

Thank you!
