Error processing uploaded data (Report ID: 3256f6c4)

I have been having problem with sync my library in both Zotero Standalone and Firefox. Below is the error report. It is not uploading data to the server. (I don't see newly added items online) Any help would be appreciated. Thanks.

I needed some additional debug output for this. Can you trigger a sync again? No additional error report needed.

aioria

Just did.

It seems you somehow changed an attachment from being an imported file (within the Zotero storage directory) into a linked file stored elsewhere on your disk? The Zotero sync server doesn't currently support changing of attachment link modes.

We might be able to support changing attachments between imported and linked files, but I'm curious how you did this.

The parent item of the attachment in question (though there could be more than one) has a Date Modified of "2011-01-17 16:59:26".

Originally I was using imported files as attachment. Then I switched to linked files mostly for syncing those files via dropbox. For those items with imported files, I wrote a python script to modify the zotero.sqlite database file - changed the link mode and updated the file path. I did this about 7 months ago. It has been working fine until recently. Any idea how to solve the problem?

OK, you should never modify the database directly.

It would only have been working fine because you didn't modify the items' mod times and the changes were therefore never synced to the server. Syncing items with changed link modes never would have worked. Once something triggered the syncing of those items, you'd get this error. It looks like the item in question was modified a month ago.

Your best bet, short of undoing all of your link mode and path changes, is to wait and see if we can add support for changing between these two link modes. I can't do that at the moment, but I'll try to look into it in the next day or so. It might require client changes as well for such syncs to not then just cause errors in other synced clients.

dstillman

(For what it's worth, Direct Access to the Zotero SQLite Database includes a warning against modifying the database directly. This used to be phrased more clearly before it was reworked by a community editor. I'll update the page to make the warning more explicit.)

aioria

Thanks for the explanation. So would the following workaround be possible - remove all the attachments, sync with the server, link files and sync again? (or to say, if I remove the modified attachment, will the server still recognize that the link mode has been changed and thus give conflict error?)

dstillman

Deleting the affected attachments and relinking them as new attachment items would be fine. Remember to empty the trash.
