Re,
I take a look on the source code where this msg happen
https://github.com/apache/lucene-solr/blob/master/solr/core/src/java/org/apache/solr/schema/SchemaField.java#L186
I use version 6.5 who differ from master.
In 6.5:
if (! (indexed() || hasDocValues()) ) {
As my field is not indexed (and hasDocValues() is false as binary),
this test fail.
Ok but so, what is the way to get this field as I can see it in Luke
(in hex format) ?
