API call

Hi,

I got a konnected device linked to my hassio server.

I wouls like to add the uptime and software version in hassio.

I saw that we can call konected rest api to get thoses values.

Before integrating this, I am trying to do a curl call.

curl -X GET http://<home assistant ip and port>/api/konnected/device/<mac address of konnected>

but I always get this error:

500 Internal Server Error

Server got itself in trouble

Any idea what I am doing wrong?

Thank you
