Currently, the ReportDesignerControllerBase class does not enforce its own JsonSerializerSettings, rather it uses the ones set globally, on the application level. This could potentially lead to errors since the Web Report Designer requires the data to be serialized in camelCase. When PascalCase is used, certain functionalities get broken.

A way to avoid this would be to explicitly define JsonSerializerSetting in the ReportDesignerControllerBase class so that the Report Designer service does not break regardless of the setting defined on the application level.
