- Set the browser to language 'Spanish (Latin America)' ('es-419')
- As a public user, open a livechat session.
The session doesn't open.
The root cause is the creation of a mail channel which contains
translatable fields (e.g. name). This attempts to create translations
in the 'es_419' language. However, this locale doesn't exist in Odoo,
and it triggers the constraint 'lang_fkey_res_lang'.
In this specific case, there is no real reason to translate the channel
name. Therefore, we simply avoid it thanks to a context key.
