How to enable authentication in hyperledger Angular application

0 votes

I have deployed hyperledger composer blockchain to multiple organizations by following this tutorial which is successful.

I have generated angular2 app by using command yo hyperledger-composer:angular by selecting options use existing network and generate new rest api.

When I start application it is successful and I can browse assets and participants from hyperledgercomposer using URL http://localhost:4200

Now I want to enable rest authentication for which I have installed passport-github and configured export option by following this tutorial and edited package.json file of angular2 app as below so that authentication is enabled at start

 "app": "composer-rest-server --card admin@some-network -n never -p 3000 -m true"

I have added -m true option so that authentication is enabled by default when I start angular2 app using npm start command.

When I start application I get below error. How to resolve this?
