I am using the Ebook Compiler v1.3.2 (ebookc-1_3_2-plus-fop.zip).
When I compile my ebook using the command
./bin/ebookc -fop ./plus/fop-2.3/fop/fop ExperimentsTutorial.ebook
ExperimentsTutorial.pdf
Note that if you have installed the "ebookc-1_3_2-plus-fop.zip"
distribution, there is no need to specify "-fop ./plus/fop-2.3/fop/fop".
Ebookc will automatically find the bundled FOP.
I receive the following error

Yes, that's right.
I commented out the "margin-top: auto;" in the CSS file (see the
ebook.css file attached) and the Ebook compiles successfully.
I then remove the comments to the "margin-top: auto;" statement in the
CSS file and used the XMLEditor to convert the same Ebook to PDF.
Surprisingly the conversion was successful even with the margin-top set
to auto.
Ebookc and XMLmind XML Editor behave the same in that respect. The only
difference is that you haven't noticed the FOP errors reported by
XMLmind XML Editor. See attached screenshot showing XMLmind XML Editor
command execution log. (More info here:
https://www.xmlmind.com/xmleditor/_distrib/doc/help/statusTool.html)
I would like to continue using the Ebookc instead of the XMLEditor to
convert the Ebook to PDF, so I can automate the process. Hence, is there
a workaround to use Ebookc and have the margin-top set to auto?
These "Invalid property value" errors are specific to FOP and you can
ignore them. They are not fatal errors. The PDF file is anyway
successfully generated. Therefore you may continue using ebookc.
--> If you really want to suppress these ugly errors, simply add a
"@media FOP" block as a workaround. We already did that for
margin-left=auto and margin-right=auto. Example:
---
@media FOP {
/*
* FOP complains about margin:auto.
*/
.xmtable,
table[border="1"],
figure {
margin-left: 0;
margin-right: 0;
}
}

--> Alternatively, XMLmind XML Editor may be used as a command line
tool. The command line version of XMLmind XML Editor is called
"xxetool". See "The xxetool command-line utility".
