According to the transaction documentation

Marks a method in an abstract Dao class as a transaction method.

Change your class to:

@Dao abstract class Dao {

    @Insert(onConflict = REPLACE) abstract fun insertList(chacaras: List<String>)

    @Query("SELECT * FROM chacara WHERE cityId = :cityId")
    abstract fun getListOfCity(cityId: String): LiveData<List<String>>

    @Delete abstract fun deleteList(chacaraList: List<String>)

    @Transaction
    open fun updateList(list: List<String>){
        deleteList(list)
        insertList(list)
    }

}
