Exporting bib file can successfully be useful and insert citation is ok, but once clicking "Connect and load libraries", it crashed.

[qq1307229333]

I think I conducted the correct procedures according to methods.
Firstly, I exported .bib file named "references.bib" at my folder D:/tests/.
Then, In Rstudio, I clicked Addins -> insert citations one by one.

And here displayed ok, I think.

Here displayed good in Rstudio and word, too.

However, I started to click Connect and load libraries because I want to use the function of syncing Zotero items (I even don't want to exported .bib file, firstly). As you can see the words:"If you are using Zotero citr can access your reference database directly."

But the result is error and throw up the messages.

> citr:::insert_citation()

It's so weird. Hope you can help me solve it, thank you.

What I had done are:

1. update Rstudio and packages related to citr.
2. Better BibTex installed.
3. YAML code:

bibliography: ["references.bib"]
output: word_document

Can confirm this crash - is there a limit on the size of zotero libraries which can be read in this way?

[stainesa]

So,
I found I had three Group libraries with no records.
load_betterbiblatex_bib crashed on the first of these, so I removed that one
Then it crashed on the second so I removed the other two, so that every group library in my Zotero had records in it.
load_betterbiblatex_bib then worked, generating a large BibEntry object ( list of lists)..

Suggest you have a look and see if you have empty libraries?

I then tried the citr Shiny window, and I note that there is a settings button, which allows one to choose the Zotero libraries to be installed. In practice there seems to be no way to pull out a single Zotero collection.

This now works, but I note that it switches off after entering one reference. This won't work too well for large Zotero libraries, which can take a minute or two to load.

[stainesa]

suggest you investigate rbbt - may work better for the moment for both our use cases?

I had the same problem, it seems to have been solved by removing "abstract" and "notes" from the exported fields in zotero as described in the known problem section of the readme.

It goes in the direction of the library being too big to import
