PGEtinker build hangs when including a PGEX

[sigonasr2]

When trying to utilize a PGEX, the build just hangs with a 400 error in the browser console and the player shows a green screen. The Build & Run button also no longer is useable, and the user is forced to refresh the page.

Sample code (trying to include the splash screen. Utilizing any PGEX results in a similar problem.)

#define OLC_PGE_APPLICATION
#include "olcPixelGameEngine.h"
#include "olcPGEX_SplashScreen.h"

#if defined(__EMSCRIPTEN__)
#include <emscripten.h>
#define FILE_RESOLVE(url, file) emscripten_wget(url, file); emscripten_sleep(0)
#else
#define FILE_RESOLVE(url, file)
#endif

// Override base class with your custom functionality
class Example : public olc::PixelGameEngine
{
public:
    Example()
    {
        // Name your application
        sAppName = "Splash Screen Example";
    }

    olc::SplashScreen splash;

public:
    bool OnUserCreate() override
    {
        // Called once at the start, so create things here

        // built with emscripten, maps the url to the virtual filesystem and makes it
        // available to the standard C/C++ file i/o functions without change!
        //
        // built with any other native toolchain, the macro does nothing and all file
        // access is done just as it would in any other normal scenario.
        FILE_RESOLVE("https://i.imgur.com/KdWjkwC.png", "assets/gfx/broken.png");

        renBroken.Load("assets/gfx/broken.png");

        color = RandomColor();
        return true;
    }

    bool OnUserUpdate(float fElapsedTime) override
    {
        // Called once per frame, draws random coloured pixels
        if(GetMouse(0).bPressed)
            color = RandomColor();

        Clear(color);
        DrawRect(0,0,ScreenWidth()-1, ScreenHeight()-1, olc::YELLOW);
        DrawString(6,  6, "Hello, PGE", olc::BLACK);
        DrawString(5,  5, "Hello, PGE", olc::WHITE);
        DrawString(6, 26, "Mouse position SHOULD match\nclosely to the circle.\n\nYellow borders should ALWAYS\nbe visible\n\nLEFT MOUSE to change color.", olc::BLACK);
        DrawString(5, 25, "Mouse position SHOULD match\nclosely to the circle.\n\nYellow borders should ALWAYS\nbe visible\n\nLEFT MOUSE to change color.", olc::WHITE);

        DrawSprite(5, 100, renBroken.Sprite());

        DrawString(6, 221, GetMousePos().str(), olc::BLACK);
        DrawString(5, 220, GetMousePos().str(), olc::WHITE);
        FillCircle(GetMousePos(), 3, olc::RED);
        Draw(GetMousePos(), olc::WHITE);
        return true;
    }

    olc::Pixel RandomColor()
    {
        return olc::Pixel(rand() % 128, rand() % 128, rand() % 128);
    }

    olc::Pixel color;
    olc::Renderable renBroken;
};

int main()
{
    Example demo;
    if (demo.Construct(256, 240, 2, 2))
        demo.Start();
    return 0;
}

Update on this, the original code I provided won't normally compile since I'm missing a define and the below example does and works with PGEtinker:

#define OLC_PGE_APPLICATION
#include "olcPixelGameEngine.h"
#define OLC_PGEX_SPLASHSCREEN
#include "olcPGEX_SplashScreen.h"

#if defined(__EMSCRIPTEN__)
#include <emscripten.h>
#define FILE_RESOLVE(url, file) emscripten_wget(url, file); emscripten_sleep(0)
#else
#define FILE_RESOLVE(url, file)
#endif

// Override base class with your custom functionality
class Example : public olc::PixelGameEngine
{
public:
    Example()
    {
        // Name your application
        sAppName = "Splash Screen Example";
    }

    olc::SplashScreen splash;

public:
    bool OnUserCreate() override
    {
        // Called once at the start, so create things here

        // built with emscripten, maps the url to the virtual filesystem and makes it
        // available to the standard C/C++ file i/o functions without change!
        //
        // built with any other native toolchain, the macro does nothing and all file
        // access is done just as it would in any other normal scenario.
        FILE_RESOLVE("https://i.imgur.com/KdWjkwC.png", "assets/gfx/broken.png");

        renBroken.Load("assets/gfx/broken.png");

        color = RandomColor();
        return true;
    }

    bool OnUserUpdate(float fElapsedTime) override
    {
        // Called once per frame, draws random coloured pixels
        if(GetMouse(0).bPressed)
            color = RandomColor();

        Clear(color);
        DrawRect(0,0,ScreenWidth()-1, ScreenHeight()-1, olc::YELLOW);
        DrawString(6,  6, "Hello, PGE", olc::BLACK);
        DrawString(5,  5, "Hello, PGE", olc::WHITE);
        DrawString(6, 26, "Mouse position SHOULD match\nclosely to the circle.\n\nYellow borders should ALWAYS\nbe visible\n\nLEFT MOUSE to change color.", olc::BLACK);
        DrawString(5, 25, "Mouse position SHOULD match\nclosely to the circle.\n\nYellow borders should ALWAYS\nbe visible\n\nLEFT MOUSE to change color.", olc::WHITE);

        DrawSprite(5, 100, renBroken.Sprite());

        DrawString(6, 221, GetMousePos().str(), olc::BLACK);
        DrawString(5, 220, GetMousePos().str(), olc::WHITE);
        FillCircle(GetMousePos(), 3, olc::RED);
        Draw(GetMousePos(), olc::WHITE);
        return true;
    }

    olc::Pixel RandomColor()
    {
        return olc::Pixel(rand() % 128, rand() % 128, rand() % 128);
    }

    olc::Pixel color;
    olc::Renderable renBroken;
};

int main()
{
    Example demo;
    if (demo.Construct(256, 240, 2, 2))
        demo.Start();
    return 0;
}

However in a normal setting the compiler should still let the user know that external symbols were undefined. Maybe something for the original bad code can still be added so the app doesn't get stuck and the user is unsure why?
