Procfile Error Deploying Rails API with Dokku

Question

I am currently trying to deploy my Rails API on Dokku, I keep running into this error where it says "Proc entrypoint [procname] does not exist. Please check your Procfile". I'm not sure what the issue is and how to set up an entrypoint, I've tried searching all over and have not been able to find an example of this being implemented.

Here is the full log of when I try to push to dokku master:

       ###### WARNING:

       You set your `config.active_storage.service` to :local in production.
       If you are uploading files to this app, they will not persist after the app
       is restarted, on one-off dynos, or if the app has multiple dynos.
       Heroku applications have an ephemeral file system. To
       persist uploaded files, please use a service such as S3 and update your Rails
       configuration.
