Babylon Native for UWP - How to Debug?

Hi, currently I’m trying the Babylon Native for UWP.
The demo app works fine.
But when I try to run my full game, I have some problems.
Can you please help me with the debugging?
I’m having errors like these which are very hard to determine, where the problem is:

Exception thrown at 0x00007FFA240C3B29 in Playground.exe: Microsoft C++ exception: Js::JavascriptException at memory location 0x00000043091FC290.
Exception thrown at 0x00007FFA240C3B29 (KernelBase.dll) in Playground.exe: WinRT originate error - 0x80070057 : 'textures/heading_texture.jpg is not a valid absolute URI.'.

Uncaught Error: Unknown failure

I understand from this only error with the absolute path. But I’d like to use the relative path, based on the app file system location. Is it possible?

Thanks.

Pinging @cedric or @bghgary

To use a relative app path from the pacakge, use the app:/// syntax.
