Hi David I can reproduce your error with the Keycloak server not running so you may not be running it on the default port

npm start 

> keycloak-express-openid-client@1.0.0 start
> node index.js

node:internal/process/esm_loader:94
    internalBinding('errors').triggerUncaughtException(
                              ^

Error: connect ECONNREFUSED 127.0.0.1:8080
    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1187:16) {
  errno: -111,
  code: 'ECONNREFUSED',
  syscall: 'connect',
  address: '127.0.0.1',
  port: 8080
}

This makes sense as Keycloak's default port is 8080
Started up the keycloak server and was able to get it running

 npm start          

> keycloak-express-openid-client@1.0.0 start
> node index.js
