• Steps to reproduce the issue: In webmodule set UseHybridSerializer to false

I have tested this in a clean 4.4.0 and 4.4.2 template. The issue does not occur when i set UseHybridSerializer to true. I do not understand why this issue occurs. I have seen the JsonConverter written by maliming last year and it specifically is for Newtonsoft Json (which we still use). That code has not changed since then. What am I doing wrong.
