Protobuf-net: how to debug "Nested or jagged lists and arrays are not supported"

I got the following error during serialization:

I see a problem, but where, what type? Any suggestion how to find it?

I tried to search Dictionary<

List<

and see what's inside it, but no luck.

InnerException

- null

I tried to call ProtoBuf.Meta.RuntimeTypeModel.Default.GetSchema(typeof(LinkBudgetScenario));

the same not helpful message.

Is it possible to get a more helpful error message rather than an internal debugging useless message?

Steps to fix the problem:



  • Try looking at the original object. (if not luck goto 2

    )
  • Please bring the source code Protobuf-net

    to your solution (if not luck goto 3

    )
  • Install .net reflector

    and enable debug capability, don't forget to stop all exceptions ( Debug

    → Windows

    → Exception Settings

    ). You can now identify the type of problem.
