Python3 Quart register_blueprint of python-healthz引发异常

Question

我使用flask并尝试迁移到quart，以便从HTTP/2中获益。我使用flask-healthz进行kubernetes就绪和活动健康检查。是否有任何与flask-healthz等效的quart

我不确定它是否会工作，但尝试register_blueprint(healthz, url_prefix="/health")会抛出以下异常：

  File "/app/src/app.py", line 37, in create_app
    app.register_blueprint(healthz, url_prefix="/healthz")
  File "/home/user/.local/lib/python3.9/site-packages/quart/app.py", line 507, in register_blueprint
    blueprint.register(
  File "/home/user/.local/lib/python3.9/site-packages/flask/blueprints.py", line 322, in register
    state = self.make_setup_state(app, options, first_registration)
  File "/home/user/.local/lib/python3.9/site-packages/flask/blueprints.py", line 250, in make_setup_state
    return BlueprintSetupState(self, app, options, first_registration)
  File "/home/user/.local/lib/python3.9/site-packages/flask/blueprints.py", line 76, in __init__
    self.url_defaults.update(self.options.get("url_defaults", ()))
TypeError: 'NoneType' object is not iterable

任何建议和见解都是值得感谢的。
