Looking at some other unit tests in repo, I tried an approach using
UpdateRequest as follows.
SolrInputDocument sdoc = new SolrInputDocument( );
> sdoc.addField( "id", testChildPOJO.id() );
> sdoc.setField( "fieldName",
> java.util.Collections.singletonMap("set", testChildPOJO.fieldName() +
> postfix) );
> final UpdateRequest req = new UpdateRequest();
> req.withRoute( pojo1.id() );
> req.add(sdoc);
>
> collection.client.request( req, collection.getCollectionName()
> );
> req.commit( collection.client, collection.getCollectionName());
But this also results in the SAME Null Pointer Exception.
Looking at the source code, it looks like "fieldPath" is null below.
> AtomicUpdateDocumentMerger.getFieldFromHierarchy(SolrInputDocument
> completeHierarchy, String fieldPath) {
> final List<String> docPaths =
> StrUtils.splitSmart(fieldPath.substring(1), '/');
> ......

Any idea what's wrong here?
Thanks
