Json.NET error handling fails when serializing to specific object

Question

I'm trying to use JsonSerializerSettings for custom error handling, but when I specify the object type the error stops in runtime debugging. The "json" is no valid JSON, due to remote error that is out of my hands to change/fix.

Working:

var responseData = JsonConvert.DeserializeObject(json,new JsonSerializerSettings
{
    MissingMemberHandling = MissingMemberHandling.Ignore,
    Error = (sender, args) =>
    {
      // My error handling
    }
});

Breaks With:

Additional information: Error converting value "Received merchantid does not match a registered merchant" to type 'TransmitModels+errorData'. Path ...

TransmitModels.errorData responseData = JsonConvert.DeserializeObject<TransmitModels.errorData>(json,new JsonSerializerSettings
{
    MissingMemberHandling = MissingMemberHandling.Ignore,
    Error = (sender, args) =>
    {
      // My error handling
    }
});

You need to call

args.ErrorContext.Handled = true;

in your callback to tell Json.NET that you handled the exception. If you don't (maybe because you just want to log the error), the exception is thrown after your callback.
