Customizer Problem

I’ve switched my new theme to the Customize Options system and theme check is giving me the following error.

“REQUIRED: Found a Customizer setting that had an empty value passed as sanitization callback. You need to pass a function name as sanitization callback.”

All my “sanitize_callback”‘s are not empty but the “sanitize_js_callback”‘s are empty. When I put in sanitize_js_callback => ‘k’, the theme passes.

What gives?
