HarmonyOS 标准化数据通路删除异常

报错主要是直接调用删掉方法是没有数据的，抛出了异常，需要先insert数据再进行删除。

示例参考如下：

import { unifiedDataChannel, uniformTypeDescriptor } from '@kit.ArkData';
import { BusinessError } from '@kit.BasicServicesKit';
import { promptAction } from '@kit.ArkUI';

@Entry
@Component
struct Index {
  @State message: string = '删除';

  build() {
    Row() {
      Column({ space: 10 }) {
        Button("insert").onClick(() => {
          this.insert()
        })
        Button("delete").onClick(() => {
          this.delete()
        })

      }.width('100%')

    }.height('100%')
  }

  insert() {
    let plainText = new unifiedDataChannel.PlainText();
    plainText.textContent = 'hello world!';
    let unifiedData = new unifiedDataChannel.UnifiedData(plainText);

    // 指定要插入数据的数据通路枚举类型
    let options: unifiedDataChannel.Options = {
      intention: unifiedDataChannel.Intention.DATA_HUB
    }
    try {
      unifiedDataChannel.insertData(options, unifiedData, (err, key) => {
        if (err === undefined) {
          console.info(`Succeeded in inserting data. key = ${key}`);
        } else {
          console.error(`Failed to insert data. code is ${err.code},message is ${err.message} `);
        }
      });
    } catch (e) {
      let error: BusinessError = e as BusinessError;
      console.error(`Insert data throws an exception. code is ${error.code},message is ${error.message} `);
    }
  }

  delete() {
    // 指定要删除数据的数据通路枚举类型
    let options: unifiedDataChannel.Options = {
      intention: unifiedDataChannel.Intention.DATA_HUB
    };

    try {
      unifiedDataChannel.deleteData(options, (err, data) => {
        if (err === undefined) {
          console.info(`Succeeded in deleting data. size = ${data.length}`);
          for (let i = 0; i < data.length; i++) {
            let records = data[i].getRecords();
            for (let j = 0; j < records.length; j++) {
              if (records[j].getType() === uniformTypeDescriptor.UniformDataType.PLAIN_TEXT) {
                let text = records[j] as unifiedDataChannel.PlainText;
                console.info(`${i + 1}.${text.textContent}`);
              }
            }
          }
          promptAction.showToast({ message: '删除成功' })
        } else {
          console.error("message" + JSON.stringify(err, Object.getOwnPropertyNames(err), 2))
          console.error(`Failed to delete data. code is ${err.code},message is ${err.message} `);
          promptAction.showToast({ message: '删除失败' })
        }
      });
    } catch (e) {
      let error: BusinessError = e as BusinessError;
      console.error(`Delete data throws an exception. code is ${error.code},message is ${error.message} `);
      promptAction.showToast({ message: '删除失败' })
    }
  }
}
