Resource and behavior packs fails to load without user feedback

Resource packs and behavior packs that works fine in a local world, fails silently on Realms. There's no feedback to what the user needs to do to make their content packs work without failure.

I've searched your other reports, but i can't find anything on why this addon wont work. It's a sweep mimic addon that works perfectly fine on local, creator has verified a unique UUID and updated version number for TODAY's release even. Tried both 1.14 and 1.14.1, neither worked. I went through the entire addon faq sheet with him also. Would greatly appreciate an answer or i'm going to have to give up developing content.
