Webpacker::Manifest::MissingEntryError in Pioneers#index Error on Rails

Good evening
I need your help please, Im a newbie at web applications and i am taking a course and i was struggling the web server to get to work
this is when the webeserver is up:
ubuntu@ubuntu-N53SV:~/hello_WWW$ rails server
=> Booting Puma
=> Rails 6.0.0 application starting in development 
=> Run `rails server --help` for more startup options
Puma starting in single mode...
* Version 3.12.1 (ruby 2.6.3-p62), codename: Llamas in Pajamas
* Min threads: 5, max threads: 5
* Environment: development
* Listening on tcp://localhost:3000

because rails use sql lite i typed the below commands to create a table and a schema:

rails generate scaffold pioneer first_name:string last_name:string
   rake db:migrate

everything was ok so far until i opened the browser and typed: http://localhost:3000/pionners it yield a lot of errors_

ActionView::Template::Error (Webpacker can't find application in /home/ubuntu/hello_WWW/public/packs/manifest.json. Possible causes:
1. You want to set webpacker.yml value of compile to true for your environment
   unless you are using the `webpack -w` or the webpack-dev-server.
2. webpack has not yet re-run to reflect updates.
3. You have misconfigured Webpacker's config/webpacker.yml file.
4. Your webpack configuration is not creating a manifest.
Your manifest contains:
     6:     <%= csp_meta_tag %>
     8:     <%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
     9:     <%= javascript_pack_tag 'application', 'data-turbolinks-track': 'reload' %>
    10:   </head>
    12:   <body>

In the Root directory of the application i searched all elements contain the word pioneer so :

ubuntu@ubuntu-N53SV:~/hello_WWW$ find ./ -name *pione*

Could you explain me what this error is about? or what did i do wrong? or give me a shed light all what this is about.
As i told you this is the first time i experiment it and whenever errors came up i dont know how to deal with or how to put out that fire

Thanks for your help in advanced
