This concerns file provider framework on macOS.
Some users of our application (Egnyte.app) report that they have problems downloading dataless files. When a file reaches invalid state, trying to open or download it through Finder results in "Invalid argument" alert (see example-recording.mp4). At the same time our FileProvider extension receives no fetchContents or fetchPartialContents calls.
A step-by-step set of instructions to reproduce the problem (if possible) So far we don't have clear reproduction steps. The issue is easily reproducible, for multiple files, for some of our customers. See attached sysdiagnose and recording.
What results you expected Our extension receives a request to download the file. File downloads and opens successfully.
What results you actually saw No download request made to our File Provider extension. File doesn't open, Finder alert instead.
PLEASE NOTE: Before recording and collecting sysdiagnose we installed FileProvider.mobileconfig, slightly modified official profile that we attach. Example reproduction happens 8:33 into full-recording.mp4, around 17:01:18 / 17:01:19 machine’s time. Shared sysdiagnose and recordings come from one of our customers, they permitted us to share the data. In the recording they try to open files with multiple 3rd party applications (Vectorworx, Office PowerPoint) and those opens fail with alerts from those applications. We have similar reports from customers using Adobe apps.
