I built a Solr 8.10.1 server and when I try to upload documents to a
Solr collection in 8.10.1, I get a "Data is invalid at root level"
error. Any help with would be appreciated.
Scott's answer is very likely the problem. Solr switched to JSON as the
default response writer in version 7.0. Before that it was XML.
You can either add a "wt" parameter set to "xml" in the SolrNET code, or
add it to the defaults section of the handler definition in
solrconfig.xml. I have no idea how to get SolrNET to do it ... that
client is third party, not developed by the Solr project.
The solrconfig.xml file developed by the dovecot team for their Solr
integration has this as a top-level element (subordinate only to the
"<config>" element) to switch the default back to XML:
<queryResponseWriter name="xml"
default="true"
class="solr.XMLResponseWriter" />
Thanks,
