Error in data.frame: arguments imply differing number of rows

I don't know if this is a bug.

Describe the bug
I am using rmarkdown and citr with RStudio. When I connect citr with Zotero, it returns the following error message:

`citr:::insert_citation()

I am also getting this same issue

Restarting R and reloading Zotero seems to have fixed this for me.
