How to hide argument value in success job details?

My application enqueue jobs with argument List<SomeClass> where SomeClass is deserialized from JSON by newtosoft Json.NET. Like this:

BackgroundJob.Enqueue(() => myJob.jobStartMethos(List<SomeClass> argument));

When open success job details i’ve see:

using my.namespace

MyJobClass myJob = Activate<MyJobClass>();
   new { FromJson<SomeClass>("json string"), FromJson<SomeClass>("json string") ... etc...

This argument is too large and really prevents to browse details. How i can fix this? I tryed to override toString() but this doesn’t help.
And I tryed

JobHelper.SetSerializerSettings(new JsonSerializerSettings
                    TypeNameHandling = TypeNameHandling.None

But this doesn’t help.
