after understanding remove has issue realmobjects having associations other objects, modified code follows, still no luck

val deleteddependent = realm.where(user::class.java)?.equalto("id",deletedependentdata.dependentuuid)?.findfirst()         info("dependent id=>${deleteddependent?.id}")         info("dependent id=>${deleteddependent?.sessions}")          info("dependent id=>${deleteddependent?.secondarycaregivers}")         realm.executetransaction {             //deleteddependent?.removefromrealm()              val dependentsessions = deleteddependent?.sessions             dependentsessions?.let {                 for(sess in dependentsessions) {                     if(sess.temperature != null) {                         sess?.temperature?.removefromrealm()                     }                       if(sess.heart != null) {                         sess?.heart?.removefromrealm()                     }                       if(sess.lungs != null) {                         sess?.lungs?.removefromrealm()                     }                       sess?.removefromrealm()                  }             }              deleteddependent?.sessions = null              deleteddependent?.primarycaregiver = null              deleteddependent?.secondarycaregivers = null              deleteddependent?.removefromrealm()          }  did face issue , resolved it?
