This issues happens because colormap module on which ncwms depends is not instantiation the coverage reader with the coverage info. In consequence only no-data dimension will be available, since the ncwms needs to access actual data the following exception is returned:

<?xml version="1.0" encoding="UTF-8" standalone="no"?><!DOCTYPE ServiceExceptionReport SYSTEM "http://localhost:8080/geoserver/schemas/wms/1.1.1/WMS_exception_1_1_1.dtd"> <ServiceExceptionReport version="1.1.1" >   <ServiceException>
