HarmonyOS context在worker中传递报错？

Question

代码如下

@Sendable
export default class InsertMsgDbModel {
  public tableName: string = '';
  public dbName: string = '';
  public userId: string = GlobalConf.channel;
  public sendableContext: sendableContextManager.SendableContext;
  constructor(sendableContext: sendableContextManager.SendableContext) {
    this.sendableContext = sendableContext;
  }
}

let sendableContext: sendableContextManager.SendableContext = sendableContextManager.convertFromContext(this.context);

const insertDbModel = new InsertMsgDbModel(sendableContext);
private workerStage1: worker.ThreadWorker = new worker.ThreadWorker('ZhBaseLib/ets/workers/ZHBaseWorker.ets');

this.workerStage1.postMessage(insertDbModel);

删除sendableContext 后可以正常传递，加上后提示序列化失败。按官方文档应该是支持的。

使用sendableContext需要配合使用postMessageWithSharedSendable方法，这边看您使用的是postMessage，可尝试替换为postMessageWithSharedSendablesendableContextManager.convertFromContext的示例中使用的也是postMessageWithSharedSendable，请替换使用
