scyllaDB scala driver phantom store method throwing exception/error

i am following this guide and using the same code but in sbt 1.2.8 the code for store method is giving an error message

 case class Mutant(
                   firstName: String,
                   lastName: String,
                   address: String,
                   pictureLocation: String

             )


   abstract class Mutants extends Table[Mutants,Mutant] {
      override def tableName: String = "mutant_data"
    
      object firstName extends StringColumn with PartitionKey {
        override def name = "first_name"
      }
    
      object lastName extends StringColumn with PartitionKey {
        override def name = "last_name"
      }
    
      object adress extends StringColumn
    
      object pictureLocation extends StringColumn {
        override def name = "picture_location"
      }
    
    }

`class MutantsDatabase(override val connector: CassandraConnection) extends` Database[MutantsDatabase](connector) {
          object mutants extends Mutants with Connector
        }
      

class MutantInsert {

        val connection: CassandraConnection =
            ContactPoints(List("scylla-node1:9042", "scylla-node2:9042", "scylla-node3:9042"))
              .keySpace("catalog")
    
    val db = new MutantsDatabase(connection)
    import db.{session, space}
    
        val insertionResult:Future[ResultSet] = db.mutants.store(mu).future()
    
    }

when i compile the code i got the error message

value future is not a member of com.outworkers.phantom.builder.query.InsertQuery.Default[db.cql.Mutants,models.Mutant]

when i add this import statement

import com.outworkers.phantom.dsl._

the error goes away but i got a run time exception on the same store method line

java.lang.ClassCastException: Cannot cast scala.concurrent.impl.Promise$Transformation to com.outworkers.phantom.ResultSet
