Hi [[email protected]],

So the Solr connector get a response code 400 with the "missing content stream"
message status. After debugging the code I found that after the following lines
:(
SolrParams params = request.getParams();
RequestWriter.ContentWriter contentWriter =
requestWriter.getContentWriter(request);
Collection<ContentStream> streams = contentWriter == null ?
requestWriter.getContentStreams(request) : null;
The 'streams' collection object which should NOT be null and should contain the
inputstream of the incoming file, IS null. And this is due to the fact that the
contentWriter object is not null
> Solr Connector is unable to ingest documents

> Key: CONNECTORS-1533
> URL: https://issues.apache.org/jira/browse/CONNECTORS-1533
> Project: ManifoldCF
> Issue Type: Bug
> Components: Lucene/SOLR connector
> Affects Versions: ManifoldCF 2.11
> Reporter: Julien Massiera
> Assignee: Karl Wright
> Priority: Major
>
> The "r69acbd9 - Fix solr connector content deletion bug" has introduced
> another bug :
> It is now impossible to ingest documents into Solr 7.4.0, we obtain the
> following error : Error from server at http://localhost:8983/solr/FileShare:
> missing content stream
> The fact is, the requestWriter.getContentWriter(request) object is equal to
> null only on commit requests. So the new lines of code introduced by the fix,
> which are based on the test of this object, result in a null
> Collection<ContentStream> streams object and so the update request is failing.
> Concerned class :
> org.apache.manifoldcf.agents.output.solr.ModifiedHttpSolrClient
