LibGDX - Application crashes when call TiledMapRenderer.render()
===

    @Override
    public void render(float delta) {
        Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);

        camera.update();
        sprite.setProjectionMatrix(camera.combined);
		
        mLevel.getTiledMapRenderer().getProjectionMatrix().set(camera.combined);
        Vector3 tmp = new Vector3();
        tmp.set(0, 0, 0);
        camera.unproject(tmp);
        mLevel.getTiledMapRenderer().render(tmp.x, tmp.y, camera.viewportWidth, camera.viewportHeight);

        sprite.begin();
        ...
        sprite.end();
    }

Here is what I get when launching the desktop version :

    Exception in thread "LWJGL Application" java.lang.IllegalArgumentException: Number of remaining buffer elements is 0, must be at least 1. Because at most 1 elements can be returned, a buffer with at least 1 elements is required, regardless of actual returned element count

I've tried both [this tuto][1] and [this one][2], and I get the same error at the same line `mLevel.getTiledMapRenderer().render(tmp.x, tmp.y, camera.viewportWidth, camera.viewportHeight);`.
