error: failed to push some refs to 'https://git.heroku.com/covid19-forecast-kerala.git' ```
#### Solution
Run `heroku builds:cancel`. Then run `git push heroku main`
### 2. Failed to find attribute 'server' in 'app'
Check gunicorn run from local machine: `gunicorn app:server --preload -b 0.0.0.0:5000 ` Run this command from the same folder.
Add `server = app.server` under `app = dash.Dash()` in `app.py`
