I have a free recall experiment that I am trying to deploy on Heroku. It works fine locally, but when I deploy it on Heroku it does not work. I get "Method Not Allowed" error when it is trying to access trials for participants through flask code. I previously had the same experiment running perfectly on Heroku, but it is not working at this time. I tried several things like reverting back to previous working version of the experiment, creating a new Heroku app and going through all the process again, but that does not seem to work. Has anyone else faced this kind of issue recently and have managed to find there way around? Please let me know.
