Trying my best to grind through and figure this out

I am trying to do my first successful nodered automation. through reading and youtube I have gotten pretty far… but why am I getting this errror? When i search there is a zillion different reasons…

I am just trying to turn on two strips of LEDS, using WLED and set them to preset 4 at sunset every day. I was going to go from there, but I dont want to move forward without knowing whats going on… even though things seem to be working ok, it is still throwing up an error…

I was thinking how node red was going to be so easy, but it seems a bit overwhelming!

Thanks In Advance

You still need to format the data portion, like you would in an automation. Normally you could click the load example and it would fill in the data field with the available options but it is not working now.

{"preset":4}
