Please help me sort out this resource pack

[coshnaut]

I have an in-progress server that needs resource pack treatment in order to play, but it hasn't been working at all.

The pack works totally fine in singleplayer, or even client side while playing on the server, but not through the server resource pack. But, when I join the server with the resource pack enabled (server side), I get this message: 

It doesn't appear in any of the other scenarios.

The resource pack consists of

• some textures
• model files
• custom model data files

I do plan on making changes to the resource pack
