It works perfectly fine locally when I am running it. I'm not entirely sure why I am getting the @app.route('/', methods['GET']) because I don't even have the endpoint created. Any help would be great thanks.

My file structure is 

api/ 
   app.py 
   Procfile 
   requirements.txt 
   runtime.txt 

Procfile 
web: gunicorn app:app

I did a heroku logs -t this was the result:

log says its on app/app.py line 61, so seems its your code. can you post the whole code. if that's the case, make

methods['GET'] to methods=['GET']

Thanks that actually fixed it as well as the comment below. I also had to restart the Heroku server. Thanks all!

By default, an API endpoint will be a "GET" method so instead of @app.route('/', methods['GET']) you can write it as @app.route('/') or @app.route('/', methods=['GET']). That is, if we are mentioning the method then it would be like@app.route('/', methods=["GET"])or@app.route('/', methods=["POST"])or @app.route("/", methods=["PUT"]) etc..

example:

@app.route('/', methods=["GET"])
def index():
    return jsonify({"data": [], "status": 200}), 200
