It was showing when the key of the object which was passing has the symbol ‘&’ in it. It also throws error when the key has space in between them. The special symbols should be replaced in order to successfully pass the data to the pdf. For that, the data can be passed into the following function:

function escapeXml(unsafe) {
            try {
                if (unsafe) {
                    return unsafe.replace(/[<>&'"]|- None -/g, function (c) {
                        switch (c) {
                            case '<':
                                return '&lt;';
                            case '>':
                                return '&gt;';
                            case '&':
                                return '&amp;';
                            case ''':
                                return '&apos;';
                            case '"':
                                return '&quot;';
                            case '- None -':
                                return 'Nil';
                            default:
                                return c;
                        }
                    });
                }
            }
            catch (e) {


                return log.error("error@unsafe", e.message);
            }
        }
