I am trying to deserialize this json:
{ "id" : 1, "attributes" : { "weight" : 120, "age": 20 } }
Works well with this case class:
case class Record(id: Int, attributes: Map[String, Int])
However the data has an empty string when there are no attributes:
{"id" : 2, "attributes" : ""}
Deserialization fails with this message:
Can not instantiate value of type scala.collection.immutable.Map from
String value (''); no single-String constructor/factory method
Please suggest how to get past this issue. The package version we use is:
"com.fasterxml.jackson.module" %% "jackson-module-scala" % "2.2.2"
Thanks,
Anand.
