Assertion failed: (spriteFrame != nullptr), function initWithSpriteFrame, file /Users/vv/Downloads/cocos2d-js-v3.0/frameworks/js-bindings/cocos2d-x/cocos/2d/CCSprite.cpp, line 213.

I used statement below to start the secen in main.js.
cc.director.runScene(new InitialScene.create());

Can you please advise?

Thanks,
Victor
