Missing Number, Treated As Zero

Testing the conversion of .epub to pdf and not having much luck.  I 
downloaded a random epub file to test with...

pandoc -f epub -t latex -o mytest.pdf --pdf-engine=pdflatex 
aliceDynamic.epub --verbose > epub.txt

! Missing number, treated as zero.
<to be read again>
                   \protect

                                                  \end{center}
!  ==> Fatal error occurred, no output PDF file produced!
Transcript written on C:\tex2pdf.-5080fd875f0b148b\input.log.

Error producing PDF.
! Missing number, treated as zero.
<to be read again>
                   \protect
l.90 ...enter}\rule{0.5\linewidth}{\linethickness}

The text2pdf file is just an empty folder.

Help is greatly appreciated!

You can convert to tex first:

pandoc --pdf-engine /usr/bin/xelatex -f epub -o test.tex


and then to pdf manually /usr/bin/xelatex test.tex to get the full output and error message.

The latex macro `\rule` requires two arguments, a length and a 
line thickness. The error message suggests that the macro 
`\linethickness` isn't defined. I'm not sure what could be the 
cause of that, though.

Right now i'm running Windows.

Tried it.  Here's what I'm getting for this:

C:\>pandoc --pdf-engine C:\Program Files\MiKTeX 2.9\miktex\bin\x64\xelatex 
-f epub -o text.tex
pdf-engine must be one of wkhtmltopdf, weasyprint, prince, pdflatex, 
lualatex, xelatex, latexmk, pdfroff, context

Yes, `--pdf-engine` doesn't take a file path, it just accepts a 
predefined set of engine names. The program `xelatex` should 
simply be in your $PATH. So:

    pandoc --pdf-engine xelatex  -f epub -o text.tex

No, you still need to add the file name of your input file to the 
command line. Otherwise Pandoc reads from standard input.

    pandoc --pdf-engine xelatex  -f epub -o text.tex <yourfile.md>

Ok.  Did that and got a "tex" file.  Is this converting to pdf manually?

The solution for Aaron is to update pandoc to the latest version.
