Talisman is not working when overwriting the process_response

[lipis]

In the following (minimal) app the CSP headers are not present when running the app.

from flask import Flask
from flask_talisman import Talisman


class MyFlask(Flask):
  def process_response(self, response):
    return response

# Replace MyFlask with Flask and the CPH headers will work
application = MyFlask(__name__)
talisman = Talisman(application)


@application.route('/')
def index():
  return 'Hello, world!'


if __name__ == '__main__':
  application.run(host='0.0.0.0', port=8080)

---

What would be the best way too modify the response and have the Talisman support? Is that a bug in Talisman? Am I holding it wrong?

You removed all the code that calls after functions from process_response. Don't do that, or at least call super().process_response(response) as well. Perhaps you meant to override make_response? You typically wouldn't override process_response.
