[Tex/LaTex] Why is Biblatex not working and showing “Something’s wrong–perhaps a missing \item”


I have this LaTeX document thesis.tex:



   backend=biber, babel=other   



Citing here \cite{ahu61} 





and this in library.bib:

   author={Arrow, Kenneth J. and Leonid Hurwicz and Hirofumi Uzawa},
   title={Constraint qualifications in maximization problems},
   journal={Naval Research Logistics Quarterly},
   year = 1961,
   pages = {175-191}

When I run pdflatex thesis, biber thesis and then pdflatex thesis again, I get this error:

(./thesis.aux) (./thesis.bbl) [1{/var/lib/texmf/fonts/map/pdftex/updmap/pdftex.
map}] [2]

! LaTeX Error: Something's wrong--perhaps a missing \item.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.



What does it mean? What can I do?

I am using ubuntu packages installed by apt-get.

The environment thebibliography should be used only for a “manually typed” bibliography. With \printbibliography you definitely don't need it.

So, remove \begin{thebibliography}{99} and \end{thebibliography}.
