Serializer exception after upgrading to 1.7.1 from 1.7.0

[ejsmith]

I am getting this error after upgrading. Any ideas?

Hm, I would maybe expect something like this when upgrading to 1.6.0 to 1.6.1, since that's where we upgraded our Json.Net dependency...but not going from 1.7.0 to 1.7.1.

Any chance you could provide a test that repros this?

[ejsmith]

I ended up downgrading my version and everything worked fine, but I would really like to get this resolved so that I can upgrade. Have you seen anyone else reporting this? I will try and put a repo together.

@ejsmith Sorry, for the delayed reply here. No, we haven't had anyone else report this. Could you maybe share your mapping so we can try and create a repro?

[Mpdreamz]

@ejsmith I marked the object with

[JsonObject(MemberSerialization.OptIn)]

That should fix this issue.
