indexing geofield

I'm trying to index geofield 7.x-2.0-alpha2 fields using solr 4.2 but I get this error a number of times in the log every time I'm doing drush solr-index where field_long_lat is my geofield field:

Level SEVERE Logger	SolrCore 	org.apache.solr.common.SolrException: Error while creating field 'geos_field_long_lat{type=geohash,​properties=indexed,​stored,​omitTermFreqAndPositions}' from value ',​'

org.apache.solr.common.SolrException: Error while creating field 'geos_field_long_lat{type=geohash,properties=indexed,stored,omitTermFreqAndPositions}' from value ','

I also have the drush info

I can't tell what's wrong with these nodes. It indexes until it finds these nodes, then it continues to inspect for entities (nodes in this case) for content but it won't submit the "good" nodes back to solr.

I've tried geofield 7.x-2.x dev with the same results and in combination with apache solr 3.6 with no luck.
