Hyperledger Composer BusinessNetwork Connection - 0.14.3 cannot connect - node.js

Question

I am trying to use BusinessNetworkConnection for NodeJS, but how do I get the credentials from a deployed BNA on playground and save it in my server directory?
I am getting
2017-11-03T13:07:32.83-0400 [APP/PROC/WEB/0] ERR (node:62)
UnhandledPromiseRejectionWarning: Unhandled promise rejection
(rejection id: 1): Error: Error trying login and get user Context.
Error: Error trying to enroll user or load channel configuration.
Error: Enrollment failed with errors
[[{"code":400,"message":"Authorization failure"}]]
when I try using the code
const BusinessNetworkConnection = require("composer-client").BusinessNetworkConnection;
this.businessNetworkConnection = new BusinessNetworkConnection();
this.CONNECTION_PROFILE_NAME = "ibm-bc-org1";
this.businessNetworkIdentifier = "giveback";
this.businessNetworkConnection
.connect(
this.CONNECTION_PROFILE_NAME,
this.businessNetworkIdentifier,
"admin",
"adminpw"
)
.then(result => {
this.businessNetworkDefinition = result;
console.log("BusinessNetworkConnection: ", result);
})
I have a directory /home/vcap/app/.composer-connection-profiles/ibm-bc-org1 with a connection.json file that references /home/vcap/app/.composer-credentials/ibm-bc-org1 for my credentials. The code worked for composer#0.13.2 but now I moved over to composer#0.14.3. I removed the previous credentials and created a new playground etc, everything is fresh and clean.

There is a work around when something like this happens. Because I am trying to connect with the credentials that Composer created the with admin || adminpw. You can just define a new participant in your model file and then give that participant system permissions to query and listen for events that the Historian emits.
For example in your model.cto:
participant ServerAdmin identified by serverhash {
// ServerAdmin is a type of participant
o String serverhash
}
And in your permissions.acl add :
rule ServerAdminUser {
description: "Grant business network administrators full access to
user resources"
participant: "org.acme.sample.ServerAdmin"
operation: ALL
resource: "**"
action: ALLOW
}
rule ServerAdminSystem {
description: "Grant business network administrators full access to system resources"
participant: "org.acme.sample.ServerAdmin"
operation: ALL
resource: "org.hyperledger.composer.system.**"
action: ALLOW
}
Then after the network has been deployed by Composer on playground, you can add this participant VIA the REST API, and issue it a new identity. This will give you a User ID and User Secret with which you can use in BusinessNetworkConnection.connect()
