Solr UpdateLog v4.8中的NullPointerException

我试图在Solr中更新一堆文档并提交它们：我得到了这个错误（它已经工作了很长一段时间。
我有一个多核的设置，我从一堆更新文档。我提交了我更改的所有内核。
一旦我停止并再次启动我的solr，我就可以添加并提交对象，它工作得很好。
有什么想法是错的吗？

而不是尝试使用solr的add或addBean方法
试试这个

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();
                }
            }
        }
