Need help with pets plugin

I am one of the Admins of the BuildMCPEPlus server and I was thinking of adding back the pets plugin that was stolen from the LbCore and modified by FreeGamingHere. But when I try to set my pet to something it does not work and I get an error in the Console:

Code:

Pets plugin:

 

It's build for API 2.0.0

 

I use Tesseract

 

The error is inside the plugin.

 

We don't support tesseract.
The error is caused by the plugin attempting to create a tile without the correct parameters

 

Newly spawning mobs you need to use a chunk level place, I recommend contacting the author. ()
