IntelliJ is not allowing to include node_modules folder

Hi,

I am using Intellij Ultimate 2019.1. When I opened any of my web applications, I noticed node_modules folder is automatically being excluded. I tried to unexclude it but it is not working. I googled and did following 

1. Added it as javascript library
2. Confirmed that it node_modules is not there in Editor => FileTypes => Ignore Files & Folder
3.  Verified Vue.js plugin is not installed.

But nothing helps. Can you let me know how to resolve it? Due to this I am not able to navigate to any of the library code
