I've followed the following steps: - Cloned the react app and started only front end from it. - Got the react app running on localhost:3000 - Initialized the virtual env for supertokens-python example for flask. - Started the flask server on port 3001. - Navigated to localhost:3000/ It redirected to sign-in/signup page. If I try to signin/signup, the endpoint for flask is not found Specifically getting the issue where

POST

method is not supported. I know I need to modify something in the flask app, just looking for the doc for that.
