I'm new to the process of deploying apps. I'm trying to deploy a python dash application that plots some simple graphs. The deployment process seems to have worked but it seems like there are some errors(The app works fine on localhost) and heroku suggested heroku logs --tail and here is the output for the same:

2020-04-27T05:24:56.000000+00:00 app[api]: Build succeeded

What is gunicorm? I thought it was gunicorn?! I haven't typed any bash scripts in my project.

Any help would be greatly appreciated. Thanks.

Try adding this to your code where you define the app object, if you haven't already. 

server = flask.Flask(__name__)
server.secret_key = os.environ.get('secret_key', str(randint(0, 1000000)))
app = dash.Dash(__name__,server=server,external_stylesheets=[dbc.themes.BOOTSTRAP])
