Hi,
We are trying to upgrade from Solr 4.8 to Solr 6.2.
This query:
?q=*%3A*&start=0&rows=2&wt=json&indent=true&group=true&group.field=mediaObjectId&facet=true&facet.field=rating&group.facet=true
is returning the following error:
null:org.apache.solr.common.SolrException: Exception during facet.field: rating
at
org.apache.solr.request.SimpleFacets.lambda$getFacetFieldCounts$0(SimpleFacets.java:739)
at java.util.concurrent.FutureTask.run(FutureTask.java:266)
at org.apache.solr.request.SimpleFacets$2.execute(SimpleFacets.java:672)
...
Caused by: java.lang.IllegalStateException: unexpected docvalues type
NUMERIC for field 'mediaObjectId' (expected=SORTED). Re-index with
correct docvalues type.

at
org.apache.lucene.search.grouping.term.TermGroupFacetCollector$SV.doSetNextReader(TermGroupFacetCollector.java:128)
...
The same query without the group.facet=true option does not give an
error. On Solr 4.8 the query did not give problems.
The relevant fields are configured as follows:
<fieldType name="double" class="solr.TrieDoubleField"
precisionStep="0" positionIncrementGap="0"/><field name="rating"
type="double" indexed="true" stored="true" multiValued="false"
/><field name="mediaObjectId" type="long" indexed="true" stored="true"
multiValued="false" />
Am I doing anything wrong, or do you have any suggestions on what to try next?
Best regards
Karel Braeckman
