HarmonyOS 使用UIAbilityContext.startAbility报错，错误码为16000019

使用UIAbilityContext.startAbility报错，错误码为【16000019 Can not match any component.】报这个错的原因是什么？案例如下：

try {
  console.log("Share----1")
  console.log("Share---- content:",JSON.stringify(content))
  const want = {
    action: 'ohos.want.action.sendData',
    type: 'text/plain',
    parameters: {
      [wantConstant.Params.SHARE_ABSTRACT_KEY]: content.message,
      [wantConstant.Params.SHARE_URL_KEY]: content.url,
      [wantConstant.Params.CONTENT_TITLE_KEY]: content.title,
    },
  };
  await this.ctx.uiAbilityContext.startAbility(want); // no information from API to check if sharing was successful
} catch (error) {
  this.logger.error('startAbility returned error: ' + error); // sometimes startAbility returns InternalError but shares the content correctly
}
