Long position should be opened in order to use smart sell

[Jenscaasen]

Hello,
i am getting the error "Long position should be opened in order to use smart sell". This is the request i send to /v2/smart_trades. I am trying to create a smart trade, not a smart sell, therefore i do not get why this fails with that message. Any ideas?
