An empty sequence is not allowed as the value of variable $this_schemaSpec"

When trying to create PDF documentation from the current TEI P5 source the following error is returned:

<?xml version="1.0" encoding="UTF-8"?>
<?xml version="1.0" encoding="UTF-8"?>

How to reproduce

curl -LO https://vault.tei-c.org/P5/4.9.0/xml/tei/odd/p5subset.xml
curl -X POST -F "fileToConvert=@p5subset.xml" https://teigarage.tei-c.org/ege-webservice/Conversions/ODD%3Atext%3Axml/ODDC%3Atext%3Axml/TEI%3Atext%3Axml/odt%3Aapplication%3Avnd.oasis.opendocument.text/pdf%3Aapplication%3Apdf/

I also tested this with the current TEIGarage dev at teigarage.tei-c.de version which returns the same error message.

yet another issue

as @sydb pointed out there's a duplicate XML declaration in the error response

ok, my bad: I did not specify "compiled TEI ODD" (which the P5 source is) but simply "ODD document" as input format. Yet I leave this open because we might improve the error message to something more helpful?
