Invalid$Data: Tagged Object scala.collection.immutable.List

upickle version - 0.4.4

When trying to read a nested case class, I'm getting this error of this form

upickle.Invalid$Data: Tagged Object scala.collection.immutable.List (data: [

pseudocode of what I'm trying to do

case class MyClass(
schema: MyClass1, 
data:List[MyClass2], 
stringField:String,
)

val obj = MyClass(...)
val str = upickle.default.write(obj)
val obj1 = upickle.default.read[MyClass](str)

Quite strangely, if I remove the 3rd field (stringField), it works fine.
