Helmet CSP not working correctly?

问题

Using Vue SPA distributed by Express.

this is my helmet code in express

app.use(helmet.contentSecurityPolicy({
  directives: {
   defaultSrc: ["'self'"],
   styleSrc: ["'self'","'unsafe-inline'" ,'unpkg.com', 'cdn.jsdelivr.net', 
   'fonts.googleapis.com', 'use.fontawesome.com'],
   scriptSrc: ["'self'","'unsafe-inline'",'js.stripe.com'],
   frameSrc: ["'self'",'js.stripe.com'],
   fontSrc:["'self'",'fonts.googleapis.com','fonts.gstatic.com','use.fontawesome.com','cdn. joinhoney.com']
 }
}));

Doing this produces no errors in the browser console but my page loads blank , am I missing something ?

Here is the stuff i'm trying to import in my index.html

<script src="https://js.stripe.com/v3/"></script>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/animate.css@3.5.2/animate.min.css">
<link href="https://unpkg.com/vuetify/dist/vuetify.min.css" rel="stylesheet">
