Tell us what’s happening:
Describe your issue in detail here.

I am getting this error

Error: csp must be called with an object argument. See the documentation

but I have written correctly

app.use(helmet.contentSecurityPolicy(
{ directives: { defaultSrc: [“‘self’”], scriptSrc: [“‘self’”, “trusted-cdn.com”] }} ));

Your code so far
