"tuple index out of range"

[lutefiasco]

I'm sure this is on me, but I mis-entered my Zotero UserID and API key initially. On re-running Zowie with the -a argument and a newly created API key, and then the correct Zotero UserID, I'm getting a "Encountered error IndexError: tuple index out of range." and then Zowie exits. I tried running it with the debug option, but the process fails in the same place.

I'm sure this is on me,

I managed to get the debug output, though the error still occurs.

Thanks for the report! I see the reason for the error (it's a bug -- it's not testing for a empty self.files before trying to index into it), but from the discussion on the DEVONthink forums, it sounds like the location you are trying to use is empty, which will still be a problem even after this bug is fixed. Can you tell me more about your Zotero setup? Specifically, where do the PDF files for your library live? See the Preferences, under Advanced, "Files and Folders", like the screenshot here – it would help me to know the data directory location in your setup:

[lutefiasco]

Well, it's good to know it isn't just me.

All the PDFs for my Zotero library are synced across all my devices by Box.com (provided by UCLA, where I'm faculty), which appears and functions as a regular folder in the MacOS Finder. (If anything, it avoids some of the annoying issues with iCloud requiring under-used files redownload). So, my Zotero library is in the default location, but every PDF is a "linked" attachment, and distributed across perhaps a dozen subfolders below ~/Box Sync/. So, that's the Zotero base directory. The data directory is in the default location.

Anyway, thanks for looking into the bug / issue. DevonThink is made even more amazing by having such an interested and interesting development community.

The bug caused Zowie to not complain about a missing argument. I'm fixing that now and will produce a version 1.1.1. Once that's fixed, can you try it again with something like the following?

zowie ~/Box\ Sync

or if you only want it to act on PDF files,

zowie -f pdf ~/Box\ Sync

(note the backslash for quoting of the space in the pathname). Unfortunately I've never used this "linked attachment" scheme so I don't even know what the structure looks like inside that directory. If it's full of symbolic links, we may find out it won't work without additional changes. But let's fix this argument parsing problem first.

[mhucka]

OK, version 1.1.1 is out there, if you want to give it a try. (Whenever – no rush.)

[lutefiasco]

Well, the upgrade worked. The folder is just full of real PDFs, not symbolic links, but clearly the relationship between the PDFs and the Zotero database works differently. It's possibly my use-case is fairly rare. Thanks for the fix, though.

[mhucka]

Shoot, that's too bad. The way Zowie figures out the record associated with a given PDF file is that in the other Zotero storage option, the files are in subdirectories keyed by a unique identifier, like ..../Z743PE2/some filename.pdf. Thanks to that, it's possible to ask the Zotero API about Z743PE2. Without that, I don't know how to infer the record associated with a given file.

[mhucka]

I'll ask on the Zotero forums. Maybe there's a way to do it.

In the meantime, I'm going to close this issue, as it appears the original reason (the error that arose when no argument was given) has been resolved.

Update: the Zotero forum question is at https://forums.zotero.org/discussion/comment/372519/#Comment_372519

Fixed in release 1.1.1.
