Help with mod making - what is wrong?

Hello. I’m new to VCMI and started to make a simple mod some days ago. I would like to ask somebody, who allready wrote a creature mod, or just knows how to do it. When I run the VCMI map editor it say “root data shall be object”. I don’t know where did I make a mistake. I also made another creature mod based on the Mermaid mod, and it works fine. Can somebody at least mark me the mistake? Link to mod: https://drive.google.com/open?id=1bZ6wWrr5_Os8sgi9jGDgJiAywBXkdBPd (I couldn’t upload becouse I’m new)
