Using glupload on windows with glutin and glow

Hello, I’m trying to build an app using glutin glow and gstreamer on Windows

I’m using as a reference the glupload example, I’m able to compile the app but I’m running in this runtime error:

Here's how I'm creating the gl context:

    let gl_display = gst_gl::GLDisplay::new();

    let mut shared_ctx_opt = None;

    match unsafe { app.context.context().raw_handle() } {
        piralib::glutin::platform::windows::RawHandle::Wgl(wgl_handle) => {
            println!("WGL");

            unsafe {
                let raw_handle = wgl_handle as libc::uintptr_t;

                shared_ctx_opt = gst_gl::GLContext::new_wrapped(
                    &gl_display,
                    raw_handle,
                    gst_gl::GLPlatform::WGL,
                    gst_gl::GLAPI::OPENGL3,
                )
            };
        }
        _ => (),
    };
