PHP API: previous insertBookmark code not working anymore

The code below is not longer working since the last update:
Error: InsertBookmark. Exception: Object reference not set to an instance of an object..

        $wordsApi()->insertBookmark(
            new InsertBookmarkRequest(
                "mydoc.docx", 
                new BookmarkInsert([
                    "start_range"   => new DocumentPosition([
                                                "node"      => new NodeLink(["node_id" => "0.0.0.0"]),
                                                "offset"    => 0
                                            ]),
                    "end_range"     => new DocumentPosition([
                                                "node"      => new NodeLink(["node_id" => "0.0.0.0"]),
                                                "offset"    => 0,
                                            ]),
                    "name"          => "bookmark-test",
                    "text"          => "TEST!"
                ]), 
                "my-folder
                "MY-STORAGE" 
        )); 

I can get testInsertBookmarkOnline from the test cases to work without erroring - but I can’t see why I cannot insert a bookmark using the code above with the attached document:

mydoc.docx (13.6 KB)

I am unable to notice any issue with my sample code with your attached document. However, I am looking into your code, WORDSCLOUD-2346, to find the root cause of the problem.

$requestBookmarkStartRange = new Aspose\Words\Model\NewDocumentPosition(array(
    	    "node_id" => "0.0.0.0",
            "offset" => 0,));
	$requestBookmarkEndRange = new Aspose\Words\Model\NewDocumentPosition(array(
	    "node_id" => "0.0.0.0",
	    "offset" => 0,));
	$requestBookmark = new Aspose\Words\Model\BookmarkInsert(array(
	    "start_range" => $requestBookmarkStartRange,
	    "end_range" => $requestBookmarkEndRange,
	    "name" => "new_bookmark",
	    "text" => "Some text",));
	$insertRequest = new Aspose\Words\Model\Requests\InsertBookmarkRequest(
            $requestDocument,
            $requestBookmark,
	    $folder,
            $storage
        );
	$result = $wordsApi->insertBookmark($insertRequest);
	print_r($result);
