Devices not loading in node-red-contrib-deconz


I'm using deconz and NR in docker and have installed the node-red-contrib-deconz. The initial setup of the sever was successful but when I want to list all my available decives it just shows "No matches found" and is empty.

The generated API key is also working fine and I can get the list and status of all devices.

Does anyone have an idea why no device is listed under devices?

Best regards
