Multivalued doc value field

Hi,

I am getting an error while doing a copy from a field to another but the
second field is a docValues which
I am using PersonIDSDV to run StreamingExpressions.

As I can see in this page I should be able use multivalued fields with
docValues.
https://solr.apache.org/guide/8_1/docvalues.html

Any ideas or ways to solve this?

*Error:*
Multiple values encountered for non multiValued copy field PersonIDSDV

*Schema*
<field name="DocPersonAttachS"  type="int" indexed="true" stored="true"
 multiValued="true"/>
<!-- Streammin Expressions-->
<field name="PersonIDSDV"  type="int" indexed="true" stored="true"
docValues="true"  multiValued="true"  />
<copyField source="DocPersonAttachS" dest="PersonIDSDV"/>


Thanks a lot
Sergio

Best guess:  You changed the schema file so it's multiValued, but did 
not reload the core.

Or maybe it's SolrCloud, and you changed the schema file on disk, but 
didn't upload the changes to zookeeper, or didn't reload the collection 
after uploading the changes.

The error is saying that the in-memory schema definition for that field 
on that index is not multiValued.

If there are already documents in the index with values in that field 
indexed without multiValued and you switched it to multiValued, then 
you're going to have to completely reindex after completely deleting the 
existing index directory.  This is a Lucene docValues requirement, it 
doesn't come from Solr.

Thanks,
Shawn
