hsts deprecated The "includeSubdomain" paramter is deprecated

Question

I have a loopback 3 application. When I start the application with . node I get this in my console.

hsts deprecated The "includeSubdomain" parameter is deprecated. Use "includeSubDomains" (with a capital D) instead. node_modules/loopback/lib/server-app.js:74:25

I searched in my node_modules folder, but there isn't a loopback folder. So how can I fix this?

Answer 1

It's due to the helmet config in middleware.json. Just open it, then find and replace includeSubdomain to includeSubDomains.
