Construct 2 Check failure

Check failure! This is probably a bug:
Unknown IParameter type
Condition: false
File: DataJSON.cpp
Line: 2145
Function: void __cdecl Exporter::ParameterToJSON(class std::basic_ostringstream<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> > &,class era::IParameter *,int)
Build: release 186 (64-bit) checked
Component: HTML5 exporter
(Last Win32 error: 0)
