Zotero fails to sync the database, showing the error: "Search name cannot be longer than 255 characters". I’m using WebDAV for synchronization, with the cloud storage URL set to dav.jianguoyun.com/dav.
Can you provide a Debug ID (different from a Report ID) for a sync that produces this?
But if you're getting this error, you still have a search somewhere. It's possible some plugin is hiding it, so you should make sure you've restarted in Troubleshooting Mode (Help → "Restart in Troubleshooting Mode…”), which temporarily disables all plugins.
OK, so you have a saved search with a super-long name beginning with "https://d.docs.live.net". If you don't see it, it's being hidden by a plugin when not in Troubleshooting Mode.
