COGNITIVE_SERVICE_TRANSLATE_ERROR
Have you ever seen a web page with this exact title, COGNITIVE_SERVICE_TRANSLATE_ERROR? You are not alone!
It could be because the site uses the Optimizely Languages addon and Azure Cognitive Services to auto-translate content.
There can be several reasons for this exact error message, but let's see one way we can reproduce it.
If I use Languages and try to auto-translate to a language that is not too widely used, like Norwegian Nynorsk, I'll get a translation that contains only the error code: COGNITIVE_SERVICE_TRANSLATE_ERROR.
What about the logs?

at EPiServer.Labs.LanguageManager.Business.Providers.CognitiveTranslatorProvider.Translate(String inputText, String fromLang, String toLang)The log message pinpoints the problem; the target language is not supported!
A lot of languages are supported, including Klingon – but Norwegian Nynorsk is not.
If you need to translate to a language not supported by Azure Translator, you can use my addon that uses OpenAI – or you can write your own translator provider.
