python - Error when deploying on heroku because of pkl files

Question

I am trying to deploy a flask web app on Heroku. It contains some pkl files. While I tried to deploy it to Heroku it gave me _pickle.UnpicklingError: invalid load key, 'v' so I imported joblib and changed all pickle.load() and pickle.dump() to joblib.load() and joblib.dump() and now it is giving me KeyError: 118. The project works fine on my machine either way, when I am using joblib or pickle. Can anyone please tell me what I am doing wrong? Any help would be appreciated.
