Authentication strategy simple uses unknown scheme: bearer-access-token

Question

I am using hapi-auth-bearer-token plugin for my api authentication using hapijs .

here is my code:

apiServer.register(require('hapi-auth-bearer-token'), function (err) {

    server.auth.strategy('simple', 'bearer-access-token', {
        allowQueryToken: true,              // optional, true by default
        allowMultipleHeaders: false,        // optional, false by default
        accessTokenName: 'access_token',    // optional, 'access_token' by default
        validateFunc: function( token, callback ) {

            // For convenience, the request object can be accessed
            // from `this` within validateFunc.
            var request = this;

            // Use a real strategy here,
            // comparing with a token from your database for example
            if(token === "1234"){
                //## user object to be looked up here
                callback(null, true, { token: token })
            } else {
                callback(null, false, { token: token })
            }
        }
    });
});

here is the error i am getting:

It looks like you're registering the hapi-auth-bearer-token plugin on one server ( apiServer ) then setting the auth strategy on another ( server )

Try

apiServer.register(require('hapi-auth-bearer-token'), function (err) {

    apiServer.auth.strategy('simple', 'bearer-access-token', {
        allowQueryToken: true,              // optional, true by default
        allowMultipleHeaders: false,        // optional, false by default
        accessTokenName: 'access_token',    // optional, 'access_token' by default
        validateFunc: function( token, callback ) {

            // For convenience, the request object can be accessed
            // from `this` within validateFunc.
            var request = this;

            // Use a real strategy here,
            // comparing with a token from your database for example
            if(token === "1234"){
                //## user object to be looked up here
                callback(null, true, { token: token })
            } else {
                callback(null, false, { token: token })
            }
        }
    });
});
