Why do I keep getting this null pointer exception android app kotlin My app was working fine, then all of a sudden, I started getting these null pointer errors. For some reason the alarm object is not being retrieved by the code. var alarm = alarmRepository.getAlarm(intentAlarmId.toLong()) I have no idea why.
