Group library item cannot be retrieved by Better BibTeX for Zotero plugin

What happened?

Recently, I noticed that when I'm right-clicking on Zotero reference in Zettlr to open it, it respond with "Could not open attachment. Is Zotero running?". So I started investigating the reason of this error and I found that if my Zotero reference is in a group library, then BBT plugin returns "<citekey> not found", and that's why Zettlr throw me an error message. I didn't manage to figure out if it's Zotero or BBT plugin, so I came here for a little help :)

Setup:

• Ubuntu 22.04.5
• Zettlr 3.3.1
• Better BibTeX for Zotero plugin 6.7.256
• Zotero 7.0.10

Protocol to reproduce the error:
In a terminal, type:

curl http://localhost:23119/better-bibtex/json-rpc -X POST -H "Content-Type: application/json" -H "Accept: application/json" --data-binary '{"jsonrpc": "2.0", "method": "item.attachments", "params": ["<citekey_of_your_paper_in_a_group_library>"]}'

and you may have {"jsonrpc":"2.0","error":{"code":-32602,"message":"<citekey_of_your_paper_in_a_group_library> not found"},"id":null}.

Suprinsingly, the command

curl http://localhost:23119/better-bibtex/json-rpc -X POST -H "Content-Type: application/json" -H "Accept: application/json" --data-binary '{"jsonrpc": "2.0", "method": "item.notes", "params": [["<citekey_of_your_paper_in_a_group_library>"]]}'

returns {"jsonrpc":"2.0","result":{"<citekey_of_your_paper_in_a_group_library>":["<content_of_the_note>"]},"id":null}. So I suppose that BBT plugin is able to find the paper but not the attachment (I'm note sure).

More suprinsingly, if I move the same paper to "My Library", the first command (the one with method "item.attachments") returns {"jsonrpc":"2.0","result":[{"open":"zotero://open-pdf/library/items/<zotero_ID>","path":"/path/to/zotero/data/storage/<zotero_ID>/<your_paper_name>.pdf"}],"id":null}. So I tried to cite a paper in "My Library" in Zettlr and to right-click on it and Zettlr successfully open the PDF.

I also tried to purge+reinstall Zettlr, BBT plugin and Zotero without success.

Voilà! Any idea on this bug?

Thanks in advance
