# E15009 — WhatsAppTemplateLanguageNotFound

The template version does not carry this language.

- **HTTP status**: `404`
- **Type**: `not_found_error`
- **Name**: `WhatsAppTemplateLanguageNotFound`

## What to do

The language you addressed is not one this version holds. List the version's languages to see the tags it carries, then address one of those. On an open draft you can instead add the language by saving its content; a submitted version is immutable, so there the tags it already carries are the only ones.

Operations that resolve this:
