We are upgrading several Solr instances from 9.2.1 to 9.10.1 (updating the
software and tweaking parameters in the invocation script, but leaving the data
the same for now)
Two of the collections are not allowing me to select, complaining
{
"error":{
"msg":"arrntv namedListStyle must only be used with
ArrayOfNameTypeValueJSONWriter",
"trace":"java.lang.UnsupportedOperationException: arrntv namedListStyle
must only be used with ArrayOfNameTypeValueJSONWriter\n\tat
org.apache.solr.common.util.JsonTextWriter.writeNamedList(JsonTextWriter.java:322)\n\tat...
...
"code":500
}
I notice that the select requestHandler in solrconfig.xml for these two
collections do have <str name="json.nl">arrntv</str>
But there are seven other collections in the same SolrCloud which also have
this same line in the select requestHandler in their solrconfig.xml; and they
have no problem running select; I have not yet been able to determine what
might make the difference that is special about these two collections out of
the nine collections
I plan to continue trial and error; but if anyone has a suggestion, please
advise
Thanks
