There are a few minor issues with the Get data script in the existing HPE Synergy template for 6.0.14.  I've found the following issues as well.  With these patches, it is working against OneView 6.6 & 8.0 (api versions: 3800/4600).

Our Synergy Frames are linked to a secondary directory.  As such, in the Login function we need to supply the authLoginDomain and loginMsgAck function per the API spec:

response = request.post(Synergy.params.base_url + 'rest/login-sessions', JSON.stringify({
            'authLoginDomain': 'Local',
            'loginMsgAck': true,
            'userName': Synergy.params.username,
            'password': Synergy.params.password

The API spec also calls for the Auth token to be supplied as a header to the logout function so this has been added:

if (Synergy.session_id !== null && Synergy.api_version !== null) {
            var response, request = new HttpRequest();
            request.addHeader('Content-Type: application/json');
            request.addHeader('X-API-Version: ' + Synergy.api_version);
            request.addHeader('Auth: ' + Synergy.session_id);
            response = request.delete(Synergy.params.base_url + 'rest/login-sessions');
        }

Without the logout updated I started getting the following errors:

1. HPE Synergy: Get errors (<hostname>:hpe.synergy.get.errors): Failed to receive data:
