我是商务中心的新人。我正在尝试使用 Postman 中的 POST 请求调用 REST API，它会给出这样的响应

{
    "type": "FAILURE",
    "msg": "Error calling container messageApp_1.0.0-SNAPSHOT: Error unmarshalling input",
    "result": null
}

对象“SMS”是

package com.demo.messageapp;

/**
 * This class was automatically generated by the data modeler tool.
 */

public class SMS implements java.io.Serializable {

    static final long serialVersionUID = 1L;

    @org.kie.api.definition.type.Label(value = "sendMessage")
    private java.lang.Boolean sendMessage;

    public SMS() {
    }

    public java.lang.Boolean getSendMessage() {
        return this.sendMessage;
    }

    public void setSendMessage(java.lang.Boolean sendMessage) {
        this.sendMessage = sendMessage;
    }

    public SMS(java.lang.Boolean sendMessage) {
        this.sendMessage = sendMessage;
    }

}

并且规则“RuleThree”是

package demo.messageApp;

import java.lang.Boolean;
import com.demo.messageapp.SMS;

rule "RuleThree"
    dialect "mvel"
    when
        SMS(sendMessage == true )
    then
        System.out.println( "This message is being sent" );
end

HTTP 请求是 POST 到地址：

http://localhost:8080/kie-server/services/rest/server/containers/instances/messageApp_1.0.0-SNAPSHOT

我正在使用标题：

Content-Type:application/json
X-KIE-ContentType:JSON
Accept:application/json

和身体：

{
"lookup": "ksession1",
"commands": [{
"insert": {
"return-object": true,
"object": {
"com.demo.messageapp.SMS": {
"sendMessage": true
   }
  }
 }
}, {
"fire-all-rules": "RuleThree"
}]
}

当我检查日志时，它说：

我尝试了另一个简单的项目，我得到了类似的错误。有没有人有这方面的经验？任何建议都非常感谢

谢谢你
