Json serialization errors for DiEdge for play framework 2.6.10 and play-json 2.6.0

[bha...@yantranet.com]

We recently migrated our project to play 2.6.10 with scala 2.12.5
We also updated graph-core to 1.12.5 and graph-json to 1.12.1

After the above changes , we started receiving the following error for implicit json format definitions for DiEdge

 _ must follow method; cannot follow (nodes: (String, String))scalax.collection.GraphEdge.DiEdge[String] <and> (from: String, to: String)scalax.collection.GraphEdge.DiEdge[String]
[error]   implicit val implDiEdgeFormat = Json.format[DiEdge[String]]
implicit val implDiEdgeFormat = Json.format[DiEdge[String]]

Can some one help us on how to resolve the issue.

Thanks In advance.

Which version of lift-json and paranamer do you have on your classpath?

Also, please provide complete code including your imports. In particular, what is the fully qualified type of Json?
