Java NullPointerException when saving word Document

Hi,

we are using Aspose words java-sdk :

  <dependency>
  	<groupId>local.aspose</groupId>
  	<artifactId>words</artifactId>
  	<version>17.7</version>
  </dependency>

We try to save a word document :

try (final NoBomByteArrayOutputStream bos = new NoBomByteArrayOutputStream()) {
final HtmlSaveOptions saveOptions = new HtmlSaveOptions(SaveFormat.HTML);
saveOptions.setExportHeadersFootersMode(ExportHeadersFootersMode.FIRST_SECTION_HEADER_LAST_SECTION_FOOTER);
saveOptions.setExportTocPageNumbers(false);
saveOptions.setEncoding(StandardCharsets.UTF_8);
saveOptions.setExportImagesAsBase64(true);
doc.save(bos, saveOptions); // Exception is thrown there
return bos.toUtf8String();
}

We get this exception :

java.lang.RuntimeException: java.lang.RuntimeException: java.lang.NullPointerException

I have clues on what’s going on : the problem is related with section breaks and headers/footers. When we use ExportHeadersFootersMode.NONE the document is saved without any exception.

Do you know what is the cause of this exception and how we can save the document without skipping headers/footers ?
