Bug with AZR CSL Style: context.lua:70: attempt to index a nil value (field 'cite')

[daniel-eder]

Describe the bug When trying to buid a .tex file using the example bib of the AZR csl style I run into the error "context.lua:70: attempt to index a nil value (field 'cite')".

The sample bib can be found here: https://github.com/PhilippTh/austrian-legal-citation-style/blob/master/Beispiele/Beispiele.bib In the below tex file the content is in a file "min.bib". The current official csl for AZR can be found here: https://github.com/citation-style-language/styles/blob/master/azr-abkurzungs-und-zitierregeln-der-osterreichischen-rechtssprache-und-europarechtlicher-rechtsquellen.csl In the below example it is placed as "acr.csl" next to "example.tex"

The error does not happen for all bib entries. zankl_kunstliche_2019 works, while schweighofer_rechtsinformatik_1999 causes the error. A handful of other entries seem to work, while most others also cause it.

When clearing out the bib file and leaving e.g only schweighofer_rechtsinformatik_1999 the issue remains.

For all entries that the error does not happen a correct pdf is created when running lualatex example.tex twice.

Thanks for your feedback and I can reproduce the bug. It's mainly because there is a <text variable="locator"> in the <bibliography>.

Fixed in 0afdf91.

You are a lifesaver! Many thanks. Will the issue close on next release or should I close it?

[zepinglee]

Just find your test case doesn't work with pdflatex. I'll fix it before making a release to CTAN.

You can close the issue when your local build passes.
