Sync Error: Error 412, Item has been modified, Object is out of date

acsr · January 20, 2020

I had a long running Javascript during a snapshot that stalled the app.

* That forced me to hard shutdown the app.
* Looking for the item E3MAXNZH in either local Zotero storage and WebDAV does show an item with that ID.

Did not look into the SQL-Database.

Tried to delete the possible item (from personal memory) did not help.

Sync error remains.

See Report & Debug ID below for Details

Relevant lines (from my point of view).

[JavaScript Error: "Error 412 for item E3MAXNZH in Meine Bibliothek:

ZoteroObjectUploadError: Item has been modified since specified version (expected 40790, found 40792)"]

[JavaScript Error: "Object in Meine Bibliothek is out of date -- resetting library"]

See also my last comment on the issue below on Syncing with Papership for clearance of side effects caused by 3rd party apps. https://forums.zotero.org/discussion/64967/cant-access-webdav-files-from-papership-or-zotero-org#latest

update: I tested: Syncing non breaking items of Libraries from Zotero Standalone with Zotero.org works! Manual changes in items are reflected fast. So the sync is not generally broken.

[JavaScript Error: "HTTP GET https://api.zotero.org/users/35475/deleted?since=0 failed with status code 400"]

This should resolve itself. There was just an issue with new syncs and automatic sync resets (which your Zotero needed to do) earlier today.

I can confirm that sync now has self healed the whole issues. I conflict resolution was show during the process. (Papership WebDAV sync ist working again as well) Thx for the fast response. @dstillman You are awesome...
