@shadinaif please convert the lines below into the modern code base:

RecommenderXBlock/recommender/recommender.py

Lines 952 to 964 in c05fd61

	def _get_statici18n_js_url(): # pragma: no cover
	"""
	Returns the Javascript translation file for the currently selected language, if any found by `pkg_resources`
	"""
	lang_code = translation.get_language()
	if not lang_code:
	return None
	text_js = 'public/js/translations/{lang_code}/text.js'
	country_code = lang_code.split('-')[0]
	for code in (translation.to_locale(lang_code), lang_code, country_code):
	if pkg_resources.resource_exists(resource_loader.module_name, text_js.format(lang_code=code)):
	return text_js.format(lang_code=code)
	return None

(similar to openedx/xblock-drag-and-drop-v2#365)

Also completely remove the pkg_resource translations in the deprecated PR: #77 (similar to openedx/xblock-drag-and-drop-v2#352 )

@OmarIthawi @shadinaif Is this already resolved by #77 ?

[navinkarkera]

@OmarIthawi Gentle reminder.

[OmarIthawi]

Yes @navinkarkera. Sorry for the delayed response.
