Making that same request directly over postman gives me the error message:

<?xml version="1.0" encoding="UTF-8"?>
<!-- PyWPS 4.3.dev0 -->
<ows:ExceptionReport xmlns:ows="http://www.opengis.net/ows/1.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.opengis.net/ows/1.1 http://schemas.opengis.net/ows/1.1.0/owsExceptionReport.xsd" version="1.0.0">
    <ows:Exception exceptionCode="NoApplicableCode" locator="" >
        <ows:ExceptionText>No applicable error code, please check error log.</ows:ExceptionText>
    </ows:Exception>
</ows:ExceptionReport>

If I make the request synchronous instead of asynchronous (<wps:ResponseDocument storeExecuteResponse="false" status="false">) I get:

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

    <ows:Exception exceptionCode="ServerBusy" locator="" >
        <ows:ExceptionText>Maximum number of parallel running processes reached. Please try later.</ows:ExceptionText>
    </ows:Exception>
</ows:ExceptionReport>
