LocalizedMessage

  • The Accept-Language header in the request determines the language of error messages.

  • Error responses may contain a localized message object with the locale and translated message.

  • The locale field follows the BCP 47 specification for language tags (e.g., "en-US").

  • The message field provides the error message translated into the specified locale.

If the Accept-Language header in the incoming request is not "English", then errors returned by the Apps Script API include this message. It contains the same error text translated to the requested locale.
