E15060 — WhatsAppTemplateLanguageNotInSource
The copy asks for a language the template it copies does not carry.
- HTTP status: 422
- Type: validation_error
- Name: WhatsAppTemplateLanguageNotInSource
The public API does not return this code. It comes from Bird's other surfaces, such as the dashboard, the CLI, and the MCP tools, which link here when the error occurs.
What to do
A duplicate can only narrow the languages of the template it copies, never add one. Read the source template to see the languages it carries, set include_languages to a subset of them, and add any further language to the copy afterwards. The response names the languages that did not match.
