NullPointerException From Solr UpdateLog v4.8

Question

I was trying to update a bunch of documents in Solr and commit them: I got this error (It's been working for a long time.)

I have a setup of multiple cores and I'm updating docs from a bunch of the. I commit all the cores I change.

Once I stop and start my solr again I can add and commit the object and it works fine.

Any idea whats wrong?

No, it's not the same. the code in that line is: if (entry !=null) — user1799339, Dec 07 '15 at 12:08

Instead of trying to use solr's add or addBean methods

try this

        String jsonString =
                "{\"id\":\"1\", \"title\":\"Example Document\", \"description\":\"This is an example document for Solr\"}";

        // Create Solr client
        SolrClient solrClient = new HttpSolrClient.Builder(solrUrl).build();

        try {
            // Create a ContentStreamUpdateRequest
              ContentStreamUpdateRequest request =
                    new ContentStreamUpdateRequest("/update");

            ContentStream contentStream =
                    new ContentStreamBase.StringStream(json, "application/json");
            request.addContentStream(contentStream);

            UpdateResponse response = request.process(solrClient);

            // Commit the changes
            solrClient.commit();

            System.out.println(
                    "JSON document uploaded to Solr successfully. Response status: " +
                            response.getStatus());
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            // Close Solr client
            if (solrClient != null) {
                try {
                    solrClient.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }
