Author entry without orcid key leads to Undefined control sequence
Hi,
with latest texlive, using latexmk -lualatex main
I get Undefined control sequence
errors if metadata/authors.tex
defines an author entry without an orcid id (uncomment one of the lines in authors.tex
that defines the orcid key to reproduce).
In the case of the template the PDF is still produced, so it is not a major issue, but I thought it would be better to report this.
Best, Philipp
