Module not found when initializing Chat API

#### Environment details

- OS: Windows 11
- Node.js version: 16.0.0
- npm version: 7.4.0
- `googleapis` version: ^21.0.0

#### Steps to reproduce

I'm getting the following error when trying to use the chat API. When I run npm run start I get:

```
Error: Cannot find module 'C:\Users\Martin Carrasco\Desktop\BurnoutZero\boz-google-chat-app\node_modules\https-proxy-agent\dist\index.js'. Please verify that the package.json has a valid "main" entry

requestPath: 'https-proxy-agent'
}
```

And here is my code:

```
const chat = require('@googleapis/chat');

async function createMessage() {
const auth = new chat.auth.GoogleAuth({

// Specify service account details.
keyFilename: 'credentials.json',

// Specify required scopes.
scopes: ['https://www.googleapis.com/auth/chat.bot']

});
const authClient = await auth.getClient();

// Create the Chat API client and authenticate with the service account.
const chatClient = await chat.chat({
version: 'v1',
auth: authClient
});

// Create a Chat message.
const result = await chatClient.spaces.messages.create({

// The space to create the message in.
//
// Replace SPACE_NAME with a space name.
// Obtain the space name from the spaces resource of Chat API,
// or from a space's URL.
parent: 'spaces/AAAAxqmzN8I',

// The message to create.
requestBody: { 'text': 'Hello, world!' }

});
return result;
}

// Execute function then print details about the created message.
(async() => {
const r = await createMessage();
console.log(r);
})()
```

I tried using all this node versions:
* 21.6.1 (Currently using 64-bit executable)
21.6.0
20.11.0
18.0.0
17.0.0

with no success. The only thing that worked for my was downgrading my googlechat api version to 17.0.1

Inizia riproducendo il problema con `npm run start` usando la versione ^21.0.0 di `@googleapis/chat` e ispeziona la posizione nello stack di `gaxios`, oltre ai metadati del pacchetto `https-proxy-agent` installato. Confronta lo stato delle dipendenze con googleapis 17.0.1, segnalato come funzionante; il lavoro è completato quando viene identificata una risoluzione riproducibile e viene confermato che l’inizializzazione di Chat API riesce.
