Smart value for SLA's completedCycle not working

[CSPTech]

For an automation, I am trying to get the elapsed time of a completed SLA called "Tempo de resolução"

When logged, the smart value {{issue.Tempo de resolução}} returns the following:

SlaFieldBean{completedCycle=[SlaCycleBean{startTime=SlaDateTimeBean{iso8601=Wed Dec 11 17:05:26 UTC 2019, jira=Wed Dec 11 17:05:26 UTC 2019, friendly='11/dez/19 2:05 PM', epochMillis=1576083926055}, breachTime=null, breachTime=SlaDateTimeBean{iso8601=Wed Dec 11 17:05:44 UTC 2019, jira=Wed Dec 11 17:05:44 UTC 2019, friendly='11/dez/19 2:05 PM', epochMillis=1576083944552}, breached=false, paused=false, withinCalendarHours=false, goalDuration=SlaTime{millis=14400000, friendly='4h'}, elapsedTime=SlaTime{millis=18497, friendly='0m'}, remainingTime=SlaTime{millis=14381503, friendly='3h 59m'}}]ongoingCycle=null}

However the smart value {{issue.Tempo de resolução.completedCycle}} returns nothing. What am I doing wrong?
