cucumber scala cannot construct scala option - scala

Question

I have this data in my feature in cucumber :
| deal | mir | stp1 | stp2 | date | mnt |
| 1255 | 120 | 1 | 1 | 2018-01-01 | 120 |
that I read in that case class
case class test1 (deal : String, mir: String, stp1:String, stp2: String, date: Sttring, mnt:Option[String])
in my step definition I read it like that :
Given("""^I have this data$""") {dt: DataTable =>
val dt_lists = dt.asList(classOf[test1 ])
}
Problem : when I put "mnt" which is Option[String] in my data like that :
| deal | mir | stp1 | stp2 | date | mnt |
| 1255 | 120 | 1 | 1 | 2018-01-01 | 120 |
I have an error : cucumber.runtime.CucumberException: cucumber.deps.com.thoughtworks.xstream.converters.ConversionException: Cannot construct scala.Option : scala.Option : Cannot construct scala.Option
when I retrieve "mnt" from the data:
| deal | mir | stp1 | stp2 | date |
| 1255 | 120 | 1 | 1 | 2018-01-01 |
in that case the program works.
any help is welcome thanks

I'm surprised why you want to convert dataTable to case class. If you are intended to use each field you can do something like this
`
Then("""^tGiven("""^I have this data$""") { (fieldNames: DataTable) =>
fieldNames.asList(classOf[String]).asScala.foreach { fieldName =>
// you will have all the field names here like deal,mir ,stp1 ,stp2,date,mnt
}
}
