Why am I facing a checkout UI extension deploy error in my new Shopify app?

[charles52]

I created a new shopify app and added a checkout ui extension to it using the scaffold command. When I try to deploy the app together with the extension so that I test it on a development store, I get the following error on the console

- Validation errors found in your extension toml file
└ Missing expected key(s).

The following is the shape of the shopify.ui.extension.toml

type = "checkout_ui_extension"

name = "charles-dev-checkout01"

extension_points = [

  'Checkout::Dynamic::Render'

]

[[metafields]]

namespace = "my-namespace"

key = "my-key"

# [[metafields]]

# namespace = "my-namespace"

# key = "my-key-2"

This is all that is included in the documentation https://shopify.dev/api/checkout-extensions/checkout/configuration

Which keys am I missing or how can I resolve this error?

The issue is fixed, everything is fyn in the boiler plate create by the npm commands , there was some internal issue, which i think is fixed, 

I followed the steps and was able to create first checkout ui through extensions
