I'm creating a nodejs app with paypal buttons.
The app works on local computer just fine, but I have problems with integrating it with cPanel. The application works as a server behind the passenger reverse port binding and tries to fetch data from PayPal.
I'm following paypal standard integration from https://github.com/paypal-examples/docs-examples/tree/main/standard-integration which uses node-fetch to fetch data from PayPal. And got an error on trying to create a token when the user initiates payment by clicking a PayPal 'buy now' button:
request to https://api-m.sandbox.paypal.com/v1/oauth2/token failed, reason: unable to get local issuer certificate
I've tried to resolve this error by installing syswide-cas module (which should allow me to load a whole directory with SSL certificates provided by cPanel (/ssl/certs)) but got a similar error from npm:

How to solve this issue either using syswide-cas module or not? I don't have access to a console on cPanel and don't want to use unsafe practices.
Problem solved without syswide-cas module.
What was needed was ca cert bundle ( for example one form curl.se/docs/caextract.html as Preston PHX suggested in their comment)
and SSL_CERT_FILE variable in the .env file with path to the ca cert bundle as a value.
.env:
SSL_CERT_FILE="./cacert.pem"
