I have a web filter installed on my device. The company that provides my web filter installs a custom certificate on my machine to somehow interacts with ssl and enables them to filter my web access (browsing, http requests etc.)

The problem I am getting is that when I try to install a npm package in my node application, I receive an error that the local issuer certificate cannot be retrieved.

Is it possible for me to add the certificate to npm so that it can ‘get’/retrieve it, in order to solve my issue?

Here is the relevant part of my error log:

PS C:UserssomeUserOneDriveDesktopsomeDirectory> npm i bcrypt

Thank you 🙂
