Mapbox - 无法解析图块集描述符：加载请求已取消

Question

我有以下用于下载地图区域的代码。该函数在多个区域上异步调用。在调试/开发模式下我很少收到此错误。但在生产版本应用程序中，我有时会遇到此问题，并且整个离线用户体验都被破坏了。请注意，对于用户和字段，相同的函数用于下载区域，但主要针对字段而不是用户失败。

const downloadPack = async (packName, bounds) => {
  console.log("bounds", packName, bounds);

  // Delete old pack
  await MapboxGL.offlineManager.deletePack(packName);

  const progressListener = (offlineRegion, status) => {
    if (status.state === "complete") {
      console.log(
        `Pack: ${packName}`,
        formatBytes(status.completedResourceSize),
        status.percentage,
        status.state,
      );
    }
  };

  const errorListener = (offlineRegion, err) => {
    console.log("pack error", offlineRegion, err);
  };

  const packConfig = {
    name: packName,
    styleURL: styleURL,
    minZoom: MAP_CONFIG.MIN_ZOOM_ALLOWED,
    maxZoom: MAP_CONFIG.MAX_ZOOM_ALLOWED,
    bounds,
  };

  await MapboxGL.offlineManager.createPack(
    packConfig,
    progressListener,
    errorListener,
  );

  // console.log("packConfig", packConfig);
};

我在以下区域收到以下错误：

注意最后一个包已成功下载。我什至尝试等待函数使它们同步，但我仍然收到错误。

您找到该线程的解决方案了吗？

我遇到了同样的错误，但我不知道为什么
