I've created a org.apache.spark.sql.Row where one of the fields is a List[String]. When the Row contained only values like Strings and Booleans it was parsed without any errors. However now when it contains a List[String] I'm getting the following error: 

scala.MatchError: List(, , , , ,) (of class scala.collection.immutable.$colon$colon)

I've made an attempt to convert it to a mutable collection type using .to[ListBuffer] but it did not help to solve the problem.

What is the correct way to add List[String] as a field to the org.apache.spark.sql.Row?
