Welcome to ColdBox land!
Is your dev site exactly the same as your production setup? Most notably, are you running the site in a subfolder in one location and not the other, are their mappings missing on the production server, etc?
Perhaps you can share the URL that produces that error and a little about the directory structure.
Thanks!
