Extension code not loading for development extension

[dwmil]

I have successfully packaged and uploaded a new version of our public extension with a new version number. Checking via API, the availability is "development", and status is "succeeded". I added the extension in a development-enabled property and built. When checking the launch code, though, the modules object is empty. An example with placeholder values is below. Any ideas what I did wrong?

extensions: {
    "my-extension-name": {
        displayName: "My Extension",
        hostedLibFilesBaseUrl: "https://assets.adobedtm.com/extensions/1234567890/",
        settings: {
            aaa: "123456",
            bbb: "123123"
        },
        modules: {}
    }
}

To those who may be as unknowledgeable as I am when it comes to AEP Data Collection, please be aware that if you forget to attach any rules to an extension, you will run into the situation above.
