Ive adding some extra files to my code 1 json, 1 html, 1 png and 2 python, words.pkl,classes.pkl and also chatbot_model.h5. Once i had finished with this I had tryed to do my normal push to github (was a success) and then git push heroku main. But i get the error shown above I have no branches, updated my requirements.txt and done everyone how i normally do it. But iam getting this error. No idea how on earth to fix this tried a few things like git status. But no luck, hope someone can help.

My website works fine like normal, but this commit wont go through.
