TMSFNCCloudTranslation + MS Translator API

Playing with the demo for transationg, I stumbled over this:

I managed to set the service endpoint to for which I have a valid api-key.

However, the property service region is by default set to westeurope, which shows up as:
Ocp-Apim-Subscription-Region: westeurope

But then the authorization fails. Without the Ocp-Apim-Subscription-Region: westeurope, the request succeeds.

I verified this using the RESTDebugger.

Is it possible to leave the serviceRegion empty without having it set to some default?

tx again!

We have improved this here, an empty ServiceRegion will now exclude the Ocp-Apim-Subscription-Region parameter from the request. Next version of TMS FNC Cloud Pack will have this included.

Thank you!
