illegal unit of measure in tex code created from dot2tex

I am using dot2tex to convert some graphviz into latex (pstricks) drawings. However, I get following error
! Illegal unit of measure (pt inserted). e l.21 ...newidth=1bp](0bp,0bp)(1.2057e+05bp,1028bp)
Attached is the mwe.
\begin{document}
\pagestyle{empty}
\enlargethispage{100cm}
\begin{pspicture}[linewidth=1bp](0bp,0bp)(1.2057e+05bp,1028bp)
  \pstVerb{2 setlinejoin} % set line join style to 'mitre'
\psset{linecolor=black}
  \psbezier[linestyle=dotted](89357bp,342.83bp)(89368bp,340.2bp)(89510bp,307.69bp)(89521bp,305.16bp)
