DataTransferItem Uncaught DOMException

Hello,

On Chrome (v.71.0) and not on Firefox, for some folders, I’ve this error: Uncaught DOMException

and the inspector show me the part of code which is concerned:

if (e.dataTransfer.items) {
  // Handle directories in Chrome using the proprietary FileSystem API
  var items = toArray(e.dataTransfer.items).filter(function(item) {
      return item.kind === 'file';
  });
  console.log(items);
  if (items.length === 0)
      return;
  parallel(items.map(function(item) {
      return function(cb) {
          processEntry(item.webkitGetAsEntry(), cb);
      }
      ;
  }), function(err, results) {
      // This catches permission errors with file:// in Chrome. This should never
      // throw in production code, so the user does not need to use try-catch.
      if (err)
          throw err;
      if (listeners.onDrop) {
          listeners.onDrop(flatten(results), pos);
      }
  });
}

and more specifically at the line throw err;

I’ve finally understood it was a name length problem : That concerns file with filename (path+name) with more than 260 characters (on Windows 7).

Do you understand why this Windows limit is also a limit in our case for Chrome drag&drop in Uppy dashbord (and not Firefox) ?

Thanks a lot, Aurélien

Yes. Line 42, and line 61. I’m not sure how we’d go about reporting these errors, maybe by just passing uppy.log function to webkitGetAsEntryApi? Would be nice if you looked into it.

I didn’t see any console errors with this. I could try again with some extra logging. would the readEntries function in @uppy/utils/getDroppedFiles/utils/webkitGetAsEntryApi.js be the right place to add a console.error for that?
