(ScreenCreditsWidget): Failed to find /Engine/EngineFonts/Roboto

Hello.

I encountered an error which appears in the logs when I run dedicated server build with the Cesium plugin enabled. I’m using UE v5.1.0 Source Build from GitHub and Cesium for Unreal v1.21.0. It seems to be related to the the plugin’s ScreenCreditsWidget:

This error goes away when I remove the plugin from my project. Fortunately, the error does not cause any bugs. Only a warning every time I run a server build.

I don’t know too much about the dedicated server build, but Cesium is getting the font like this:

static ConstructorHelpers::FObjectFinder<UFont> RobotoFontObj(
      *UWidget::GetDefaultFontName());

So it seems Unreal has produced a build that doesn’t actually contain the default font? Sounds like an Unreal bug to me, but I’m not sure.

Thanks. Perhaps this will be addressed in the upcoming UE 5.1 hotfixes.
