I came across this same exception when I performed a query that faceted on a field that had no documents in the index with that field. One simple case was attempting to perform faceting on an empty index.
Is it possible that no documents in your index have a value for "facet_category" at the time you are attempting to facet? For now I only create the DefaultSortedSetDocValuesReaderState if facetsCollector.getMatchingDocs().size() > 0 which protects against the case where in the index is empty, but it doesn't work if there were docs matching a different field.
