raise ValueError('invalid token in plural form: %s' % value) , ValueError: invalid token in plural form: EXPRESSION when adding new language

[Azat]

I used this guide on [stackoverflow](​https://stackoverflow.com/questions/12946830/how-to-add-new-languages-into-django-my-language-uyghur-or-uighur-is-not-su) to setup my language:

Here is my code:

# ======== support locale =========
# https://stackoverflow.com/questions/12946830/how-to-add-new-languages-into-django-my-language-uyghur-or-uighur-is-not-su
LOCALE_PATHS = [BASE_DIR / "locale"]
LANGUAGES = (
    ('en', _('English')),
    ('tr', _('Turkish')),
    ('uly', gettext_noop('Uyghur')),
    # ('uay', gettext_noop('Uyghur')),
)

EXTRA_LANG_INFO = {
    'uly': {
        'bidi': False,  # right-to-left
        'code': 'uly',
        'name': 'Uyghur',
        'name_local': 'Uyghur',  # unicode codepoints here
    },
}

When i try to run the code, it gives me this error:
