Cannot get 'Index' variant: current variant is 'Update'

[jiyong_qin]

hi @all
when i use flink(1.14.4) write data to es 8.6.2 use BulkOperation ,then something is wrong. Cannot get 'Index' variant: current variant is 'Update' and Missing required property 'BulkRequest.operations'. I don't know how to resolve. I use update, because I want to update the data according to script if it exists, and upsert if it does not.

 try {
                BulkRequest request = bulkRequest.build();//构建operation时候有异常 missing异常
                List<BulkOperation> operations = request.operations();
                checkpointState.clear();
                checkpointState.addAll(operations);
                BulkResponse result = esClient.bulk(request);
                if (result != null && result.errors()) {
                    contextRetryNum--;
                    handlePartialFailures(result);
                }
                System.out.println("执行完毕");
                break;
            } catch (ElasticsearchException ese) {
                LOG.error("write es failed:" + ese.getMessage());
                contextRetryNum = 0;
            } catch (MissingRequiredPropertyException missError) {
                //此异常证明没有操作需要进行 //超时异常也不管
                LOG.error("es sink error:{}", missError.getMessage());
                contextRetryNum = 0;
            } catch (Exception ex) {
                // 等待一段时间后重试
                LOG.error("important error:{}", ex.getMessage());
                Thread.sleep(context.getSleepTime());
            }

(BulkOperation.Builder) op
                                .update(up -> up.id(esId)
                                .index(indexName)
                                .retryOnConflict(3)
                                .action(ac -> ac.script(script -> script.inline(inLineScript -> inLineScript.source(sjson.getString("source"))
                                                        .params(params).lang("painless"))).scriptedUpsert(true)
                                                .upsert(value.getJSONObject("upsert"))

                                ));
