Streamsets Subscription for "Execution Engine not responding"

trying to configure a subscription that could alert me when any SDC doesn't respond for 2 minutes.

but getting error :

Encountered error processing EL filter in subscription <subscription_id>.

Tried with below expressions:

${(time:dateTimeToMilliseconds(time:now())-120000)>LAST_REPORTED_TIME}

${(time:dateTimeToMilliseconds(time:now())-120000)>record:value('/LAST_REPORTED_TIME')}

is there a way to do this?
