Error when deploying in heroku

[AndeYashwanth]

When I tried to deploy in heroku I got the following error in logs.
2021-04-04T15:38:17.318658+00:00 heroku[router]: at=error code=H14 desc="No web processes running" method=GET path="/" host=ejrnfkjern.herokuapp.com request_id=0bba51d3-f3ca-4667-8629-62f0e17b926d fwd="103.72.178.208" dyno= connect= service= status=503 bytes= protocol=https
I found that it could be something related to Procfile but I wasn't able to resolve the issue.
