Missing number, treated as zero

Hi, I'm trying to use this package to write a book. For now there's only one file in my bibliography. When I try to insert it into my LyX document, I get this error (five times):

<to be read again> 
                   \l@en-AU 
l.185 ...on2012classificationtextemdashcontent}}{}

A number should have been here; I inserted '0'.
(If you can't figure out why I needed to see a number,
look up 'weird error' in the index to The TeXbook.)

I'm using:

Zotero 6.0.35
TeX 3.141592653 (TeX Live 2022/Debian)
LyX 2.3.7
Jurabib 2004/01/25

Here is my LaTeX preamble:

\documentclass[9pt,a5paper,english]{memoir}
\usepackage{mathpazo}
\usepackage{avant}
\usepackage[T1]{fontenc}

\usepackage{babel}
\usepackage{jurabib}[2004/01/25]
\usepackage{microtype}

Here's the generated bibliography:

Any suggestions on how to debug this? Thanks!
