Serialization error in event log

ServiceStack Serialization
1

My network admin gave me access to our web server where my SS services are running, and I see this warning repeated multiple times in the event log (sometimes several times per minute)

Category: ServiceStack.Serialization.StringMapTypeDeserializer

Property 'ReportTypeID' does not exist on type 'DV.Svc.Model.GritEntryQuestionList'

The error message is technically correct (that property does not exist on that dto), but I’m wondering what is causing the event to fire, and why so often (I doubt it is anyone hitting the service on our beta testing site that often)

Something is trying to call your GritEntryQuestionList with the ReportTypeID parameter that doesn’t exist on the type.

It’s coming from your environment as ReportTypeID doesn’t appear anywhere in our code bases, try to see if you can track the HTTP Request that’s causing this warning.
