Hello,
Is the ‘display: flex’ fully supported when converting html to pdf using Java? We observed a case when there is an html with an empty div, and that div has a style display: flex, e. g:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<div>
<div style="display: flex;"></div>
</div>
</body>
</html>
If we try to convert the html, the following exception is thrown:
Exception in thread "main" java.lang.NullPointerException

If the div is not empty or the display value is not flex, the content is successfully converted to pdf.
The code used for conversion:
HtmlLoadOptions options = new HtmlLoadOptions();
IDocument document = new Document(RESOURCE_DIR + "input.html", options);
document.save("output.pdf");
Reproduced with 21.8 version
