I am trying to set up a bibliography with BibLatex. Even a single \cite{} statement causes an error upon second compilation with pdflatex after running biber.

The sequence of running the commands is as follows:

pdflatex mwe.tex
biber mwe (optionally multiply by 2 and/or add a bcf extension)
pdflatex mwe.tex

After running biber and trying to run pdflatex for the second time the engine errors at \cite{aa} and no bibliography gets printed.

Here is the minimal (not yet) working example:

\documentclass{article}
\usepackage[backend=biber, date=short, style=apa]{biblatex}
\title{some title}
\author{Authorov A. A.}
\date{\today}
\addbibresource{references.bib}
\begin{filecontents}{references.bib}
@misc{aa,
  author = {Some Author A.},
  title = {Some title},
  year = {2016}
}
\end{filecontents}
\begin{document}
\maketitle
Some sentence\cite{aa}

\printbibliography
\end{document}

Blg file output:

[0] Config.pm:354> INFO - This is Biber 2.7

I am running MikTex 2.9 (64-bit), Biber 2.7 and Windows 10.

Having had a look through similar questions, they either do not use Biber or the problem seems to have a different root. Would appreciate any hints and tips. Thank you in advance!

    What exactly is the error? – Joseph Wright Oct 14 '17 at 15:51
  • Upon running Biber the error is "Warn: I didn't find a database entry for 'aa'", when running pdflatex for the second time I get: "l.16 Some sentence\cite{aa}

    ! ==> Fatal error occurred, no output PDF file produced!". Judging by Biber output, it does find the bib file though: "Found BibTeX data source 'references.bib'"

  • The edit doesn't show the issue you describe: the entry is found! – Joseph Wright Oct 14 '17 at 16:03
  • Sorry about this. Probably due to minimizing this example this error has somehow dissapeared. I will edit the title accordingly for bibliography not being printed. – tasidonya Oct 14 '17 at 16:05

Here is a solution:

\documentclass{article}
\usepackage[american]{babel}
\usepackage{csquotes}
\usepackage[backend=biber, date=short, style=apa]{biblatex}
\DeclareLanguageMapping{american}{american-apa}

\begin{filecontents}{\jobname.bib}
@misc{aa,
  author = {Some Author A.},
  title = {Some title},
  year = {2016}
}
\end{filecontents}

\addbibresource{\jobname.bib}

\def\printdateextralabel{\printlabeldateextra}

\title{some title}
\author{Authorov A. A.}
\date{\today}



\begin{document}
\maketitle
Some sentence\cite{aa}

\printbibliography
\end{document}

I coopied code from here: https://tex.stackexchange.com/a/329497/120578

Posible duplicate with the above.
