OutgoingMessage.prototype._headers is depreciated, in stock price checker project

[sbrevolution5]

Tell us what’s happening:
I believe I’ve set up the helmet.js properly with the following code in my server.

app.use(helmet())
app.use(helmet.contentSecurityPolicy({directives:{defaultSrc:["'self'"], scriptSrc:["'self'"]}}))

but when I run the tests, I see the following warning in the console:

(node:920) [DEP0066] DeprecationWarning: OutgoingMessage.prototype._headers is deprecated

could this be keeping me from passing the tests? (i know functional tests aren’t complete yet)

Solved with This helpful post All it took was adding styleSrc["‘self’"] to my directives. It may be useful if this is added to the tutorial for the information security section, as I had no idea I needed to do this.
