Traccar Velocity template - add speedLimit

I tried to modify the deviceOverspeed.vm file like this to include the speedLimit in the notification popup but it does not work, it prints the variable name "$speedLimitString" instead of the speedLimit calculated value. the test that i did suggest that the $position.speedLimit is empty. what I am doing wrong? Thanks fellows

#if($speedUnit == 'kmh')
#set($speedValue = $position.speed * 1.852)
#set($speedString = $numberTool.format("0.0 km/h", $speedValue))
#set($speedLimitValue = $position.speedLimit * 1.852)
#set($speedLimitString = $numberTool.format("0.0 km/h", $speedLimitValue))
#elseif($speedUnit == 'mph')
#set($speedValue = $position.speed * 1.15078)
#set($speedString = $numberTool.format("0.0 mph", $speedValue))
#set($speedLimitValue = $position.speedLimit * 1.15078)
#set($speedLimitString = $numberTool.format("0.0 mph", $speedLimitValue))
#else
#set($speedString = $numberTool.format("0.0 kn", $position.speed))
#set($speedLimitString = $numberTool.format("0.0 kn", $position.speedLimit))
#end
$device.name exceeds the speed $speedString $speedLimitString #{if}($geofence) in $geofence.name#{else}#{end} at $dateTool.format("yyyy-MM-dd HH:mm:ss", $event.eventTime, $local>

The problem is that position.speedLimit doesn't exist.

can you suggest a alternative for my goal?

Try position.getDouble("speedLimit").

it works, thanks for taking the time !!!

any tip for showing the same thing ( actual speed and speed limit ) in the right event drawer for the overspeed event? I tried to play with the formatter.js but is seems the overspeed event has the attributes field empty
