Error in rules. Timer?

Setup, Configuration and Use Scripts & Rules
1

I have a problem with simple rules that throws me an error in openhab.log
Where I made a mistake?

import org.openhab.model.script.actions.*
import org.eclipse.smarthome.model.script.actions.Timer

var timerfan

rule "Wentylacja"		
	when	
		Time cron "0 0 0/1 * * ?" 
	then 
		if(WilgocPokoj.state > 30) {
           	sendCommand(fan, ON)
		postUpdate(fan, ON)
		timerfan = createTimer(now.plusMinutes(10)) [|
		sendCommand(fan, OFF)
		postUpdate(fan, OFF)
		]
		}
end

You’re right - thank you for your help :slight_smile:
I have one problem with warnings such as below. What is their cause?
