Gunicorn Dash Refreshing Error [BUG]

[qraxiss]

Hello, i'm created realtime crypto chart flask&dash app. My problem with gunicorn&dash combination. If i start flask "flask run". I'm not getting refresh errors. But if i start "gunicorn wsgi:app" i got refreshin errors. Let me explain the refresh error: dash callback (or whatever i don't know where is reason issue) send my chart fig and send None, but if i run app without gunicorn callback dont send None. Please help me.
