### Search before asking - [X] I had searched in the [issues](https://github.com/apache/eventmesh/issues?q=is%3Aissue) and found no similar issues. ### Environment Windows ### EventMesh version master ### What happened There may be missing some mcessary pareter configurations in the example, which causes the excample run failed. In the main method of class org.apache.eventmesh.http.demo.pub.eventmeshmessage.SyncRequestInstance, the config of httpclient and producer are as below: ``` EventMeshHttpClientConfig eventMeshClientConfig = EventMeshHttpClientConfig.builder() .liteEventMeshAddr(eventMeshIPPort) .producerGroup(ExampleConstants.DEFAULT_EVENTMESH_TEST_PRODUCER_GROUP) .env("env") .idc("idc") .ip(IPUtils.getLocalAddress()) .sys("1234") .pid(String.valueOf(ThreadUtils.getPID())).build(); eventMeshHttpProducer = new EventMeshHttpProducer(eventMeshClientConfig); long startTime = System.currentTimeMillis(); EventMeshMessage eventMeshMessage = EventMeshMessage.builder() .bizSeqNo(RandomStringUtils.generateNum(30)) .content("contentStr with special protocal") .topic(topic) .pid(String.valueOf(ThreadUtils.getPID())).build(); ``` When running this example, exceptions will be thrown in the eventmesh-runtime, and no response will be received here. I have checked all the exceptions, by reading the exception report and debugging, all information indicate that: 1. "username" and "password" in the eventMeshClientConfig can not be null or empty, but is missing here; 2. the parameter "ttl" in eventMeshMessage is required, but is missing here. I modified both of these codes with reference to the async sample code in AsyncPublishInstance, then it works fine. ### How to reproduce 1. clone the master branch to local 2. start the eventmesh-runtime with the eventmesh-starter 3. start the eventmesh-examples, run main method in SyncRequestInstance of http.demo, and no response would be received. 4. if post request with curl, it would be blocked till timeout, with no response. ### Debug logs _No response_ ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! -- This is an automated message from the Apache Git Service.
