Hi Henrik,

The reflection is ambiguous of a property. You may have a pagemodel with inherit abract property, put [JsonIgnore] on the inherited/abstract one.

We had it on DynamicProperties (legacy)

Regards!

Hmm, I have the same issue in my project and it just started to fill up the logs (App Insights).

So this has to do with inheritance of abstract classes? Anyway, I'm investigating this now.

I will get back to this thread if I find a solution or solve the problem.

Yes, it might by a normal override of properity on a page model, when missing the new key, check your warnings in VS compile. The reflector isn't that clever...
