Issue with Json response parsing, passing string to AtlassianDocumentFormat constructor.

[Luke-Arch]

JiraCloud\ADF\AtlassianDocumentFormat::__construct(): Argument #1 ($document) must be of type DH\Adf\Node\Block\Document|DH\Adf\Node\Node, string given, called in /var/www/html/vendor/netresearch/jsonmapper/src/JsonMapper.php on line  
   706

Thrown by implementation, on line 9 below (getBoardIssues call). Which appears to happen when parsing a multiline description field, when fetching board issues.

        $projectService = new ProjectService();
        $p = $projectService->get('TEST');

        //Get project boards
        $boardsService = new BoardService();
        $bs = $boardsService->getBoardList(['projectKeyOrId' => $p->id]);

        foreach ($bs as $b) {
            $issues = $boardsService->getBoardIssues($b->id, [
                'maxResults' => 10,
            ]);

            $data = [];

            foreach ($issues as $issue) {
                $data[] = [
                    'id' => $issue->id,
                    'key' => $issue->key,
                    'name' => $issue->fields->summary,
                    'description' => $issue->fields->description,
                ];
            }
        }
