"Invalid Arguments" when using Kraken BTC/USD pair

[wminno]

Using the docker install on MacOS. An older K.sh bot works fine with this install file, but the last version gives errors in the logs:

01/04 18:33:32.164294 GW KRAKEN Warrrrning: Error message: {"error":["EGeneral:Invalid arguments"]}.

Webinterface keeps reconnecting to kraken. It does show the proper trades ongoing but personal wallet never shows your balance. Tried creating new API key and hardcoding those details in the k.sh startup file inside the docker, but to no avail
