Solar Edge integration example

I have downloaded the example and connected to the inverter via tcp/modbus. But when I open the Client it shows this error message. I also tried to delete and import the example and panel several times. Anyone know why?

Seems like there is an error with the panel itself - I downloaded the template and it had sonos panel in there not linked to anything. So if you get the values from modbus you may need to make your own panel with these values.
