undefined control sequence in bibliography

Question

I'm relatively new to Latex, so I hope you'll forgive me if this question is too basic. My document will not compile due to my bibliography, and Latex gives me the following errors. I've actually run all my entries separately following this post but still cannot find where there is an issue (there's no error message in the .blg files). If anyone could offer me some troubleshooting steps, I would be grateful.

Here's a smaller bit of code that still gives an error:

\documentclass[12pt, notitlepage, twoside]{report}
\usepackage[backend=biber,style=apa,sorting=nyt,uniquename=false]{biblatex}
\addbibresource{/users/dissertation_latex/metafiles/dissertation.bib}
\begin{document}
\parencite{hawkins2002}
\end{document}

and the entry in dissertation.bib:

@inproceedings{hawkins2000,

  booktitle = {State of the {{Art}} in {{Speech Synthesis}} ({{Ref}}. {{No}}. 2000/058), {{IEE Seminar}} On},
  author = {Hawkins, Sarah and Heid, Sebastian and House, Jill and Huckvale, Mark},
  date = {2000},
