【问题描述】：
我想使用Flask-MongoEngine，它工作正常，但我试图让调试工具栏工作，当我按照文档操作时，我得到如下所示的回溯。我能够很好地运行普通的烧瓶调试工具栏，但由于我使用 MongoDB 作为数据库，我正在尝试将烧瓶调试工具栏与 MongoDB 一起使用。我知道以下行是导致此回溯的原因`
app.config['DEBUG_TB_PANELS'] = ['flask_mongoengine.panels.MongoDebugPanel']
示例代码
from flask import Flask
from flask_debugtoolbar import DebugToolbarExtension
app = Flask(__name__)
app.config['DEBUG_TB_PANELS'] = ['flask_mongoengine.panels.MongoDebugPanel']
db = MongoEngine(app)
toolbar = DebugToolbarExtension(app)
导致回溯的行
app.config['DEBUG_TB_PANELS'] = ['flask_mongoengine.panels.MongoDebugPanel']
#traceback
