Google Picker不能始终如一地加载预览图像

Question

我已设置Google文档选择器，允许用户从Google云端硬盘中选择图片或上传图片。

一旦选择器加载了一些图像＆＃39;网格视图中的预览不会加载。这似乎是随机的，错误是404（未找到）。返回404格式的url https://googledrive.com/thumb/fileId?access_token=ya....&size=180

我可以在JavaScript代码中解决这个问题吗？请参阅下面的代码。

var driveView = new google.picker.DocsView(google.picker.ViewId.DOCS_IMAGES);
driveView.setParent(driveFolderId); //sets the default displayed folder

var uploadView = new google.picker.DocsUploadView();
uploadView.setParent(driveFolderId); //set upload parent folder and prevents the user from changing it
uploadView.setMimeTypes('image/png,image/jpeg'); //image/bmp,image/gif,image/tiff 
//default file type to png and jpeg

var picker = new google.picker.PickerBuilder()
  //.enableFeature(google.picker.Feature.NAV_HIDDEN) //hide navigation
  .enableFeature(google.picker.Feature.MULTISELECT_ENABLED) // multi select - bug must be enabled to set the upload folder destination
  .addView(driveView) //allows picking files from Google Drive
  .addView(uploadView) //allows uploads
  .setOAuthToken(gapi.auth.getToken().access_token)
  .setCallback(imagePickerCallback)
  .build();

picker.setVisible(true);

提前致谢。
