How to Replace Strapi's Default WYSIWYG Editor with TinyMCE Editor

Hi, it’s me again.
I’ve got it working now, excellent job with the tutorial. Still, I’m facing a little problem which I hope someone as a solution for:

When I field is mandatory, if you try to save it no validation message appears in the interface, only a message in the js console. Is this problem solvable? thank you very much
