E15076 — WhatsAppTemplateLanguageRequired

This template requires the send to name a language.

The template sets language_source_required, so it will not fall back to its default_language: it holds a copy per language and expects you to choose the one for this recipient. Name a language from the template's available_languages. If every recipient should get the same copy, clear language_source_required on the template instead.
