Hello Luis and thank you so much for your answer! 
I tried to change to:  return response.%JSONExport() instead of:  write response.%ToJSON()

But I still get the error in the service. I can't see what is wrong.

Thanks alot for the help! :)

Another question for you Luis: Do you need to use Docker in order to implement the code in your post and everything else that is mentioned there? Or is it possible to freehand from scratch just by following what you have written? :)
Thanks beforehand!

Hello Luis! I appreciate the post very much! I will look into this directly. Seems to be the way to go. Thank you very much! :)
