升级Django4.2.1后django_plotly_dash生产环境报属性错误

将Django升级至4.2.1版本后，django_plotly_dash无法正常工作，抛出错误：'WrappedDash' object has no attribute '_generate_meta_html'。根据django_plotly_dash官方文档说明，其兼容Django版本范围为5x > Django > 3.2x，但升级后该工具仅能在本地环境正常运行，生产环境返回如下完整报错栈信息：

已尝试操作及问题定位 #

已尝试将Python升级至最新稳定版本，但问题仍未解决。定位到报错来自django_plotly_dash/dash_wrapper.py的index方法，该方法调用了不存在的_generate_meta_html属性，相关代码片段如下：

def index(self, *args, **kwargs):  # pylint: disable=unused-argument
        scripts = self._generate_scripts_html()
        css = self._generate_css_dist_html()
        config = self._generate_config_html()
        metas = self._generate_meta_html()
        renderer = self._generate_renderer()
        title = getattr(self, 'title', 'Dash')
        if self._favicon:
            import flask
            favicon = '<link rel="icon" type="image/x-icon" href="{}">'.format(
                flask.url_for('assets.static', filename=self._favicon))
        else:
            favicon = ''

            _app_entry = '''
            <div id="react-entry-point">
                <div class="_dash-loading">
                   Loading...
                </div>
            </div>
        '''
        index = self.interpolate_index(
            metas=metas, title=title, css=css, config=config,
            scripts=scripts, app_entry=_app_entry, favicon=favicon,
            renderer=renderer)

        return index
