Description

Due to Solr-14514 FacetFieldProcessorByEnumTermsStream is not used if allBuckets, numBuckets or missing parma is true.

As fallback FacetFieldProcessorByHashDV is used which FacetRangeProcessor.getNumericCalc(sf) on the field. EnumFileType is not handled currently, so a SolrException is thrown with BAD_REQUEST and 'Expected numeric field type'
