E04047 — EmailTemplateDefaultLanguageRequired

The default language has to be one of the languages the template has.

• HTTP status: 422
• Type: validation_error
• Name: EmailTemplateDefaultLanguageRequired

What to do

Set the default language to a language the template already has, or add content for the language you want to make the default. The same rule applies when you remove a language. The current default cannot be removed on its own, so point the default at a different language first, then remove the old one.
