Issue with event hub authenticate

[BLaurent]

Hi, I've apply the patch from @ThisWillGoWell,
But I am stuck just after..
Here is the sample code I am using:

Exception in thread Thread-25:
Traceback (most recent call last):

import json

import fnmatch

import predix.app
from predix.data.eventhub.publisher import PublisherConfig


matches = []

for root, dirnames, filenames in os.walk('../'):
  for filename in fnmatch.filter(filenames, 'env.json'):
    matches.append(os.path.join(root, filename))


if len(matches) == 1:
  with open(matches[0], 'r') as config :
    readConfig = config.read()
    print readConfig
    jconfig = json.loads(readConfig)

    print jconfig
    target = jconfig['target']

jservices = {}
services = os.getenv('VCAP_SERVICES')
if services != None :
  jservices = json.loads(services)

jservices['predix-event-hub'] = jconfig['predix-event-hub']
jservices['predix-uaa'] = jconfig['predix-uaa']

os.environ['VCAP_SERVICES'] = json.dumps(jservices)
os.environ['PREDIX_APP_CLIENT_ID'] = jconfig['credentials']['PREDIX_APP_CLIENT_ID']
os.environ['PREDIX_APP_CLIENT_SECRET'] = jconfig['credentials']['PREDIX_APP_CLIENT_SECRET']

logging.basicConfig(level=logging.DEBUG)
app = predix.app.Manifest()
pub_config = PublisherConfig()
pub_config.publish_type = PublisherConfig.Type.SYNC

uaa = app.get_uaa()
client_id = predix.config.get_env_value(predix.app.Manifest, 'client_id')
client_secret = predix.config.get_env_value(predix.app.Manifest, 'client_secret')
if client_id and client_secret:
  logging.info("Automatically authenticated as %s" % (client_id))
  uaa.authenticate(client_id, client_secret)

print(uaa.get_scopes())


eh = app.get_eventhub(publish_config=pub_config)

count = 0
message_id = "id-" + str(count)

acks = eh.publisher.add_message(message_id, str(count)).publish_queue()
print(acks)

The service is up I am getting the health ping, and my token is ok, both sub and pub test in golang work.

Thanks in advance
Regards

Looking into it now

Can you post your admin code?

[BLaurent]

You mean client and service creation ?

[BLaurent]

I am using this client:

 {
  "client_id": "event-hub-client",
  "scope": [
   "uaa.none"
  ],
  "resource_ids": [
   "none"
  ],
  "authorized_grant_types": [
   "client_credentials"
  ],
  "authorities": [
   "predix-event-hub.zones.af591838-8d22-474d-bcea-0953cc9d2ca0.user",
   "predix-event-hub.zones.af591838-8d22-474d-bcea-0953cc9d2ca0.topic.grpc.subscribe",
   "predix-event-hub.zones.af591838-8d22-474d-bcea-0953cc9d2ca0.grpc.subscribe",
   "uaa.resource",
   "predix-event-hub.zones.af591838-8d22-474d-bcea-0953cc9d2ca0.wss.publish",
   "predix-event-hub.zones.af591838-8d22-474d-bcea-0953cc9d2ca0.grpc.publish"
  ],
  "allowedproviders": [
   "uaa"
  ],
  "access_token_validity": 3000
 },

Also in VCAP, event-hub protocol_details is an array, I think the parser get confused

instead of

services['predix-event-hub'][0]['credentials']['publish']['protocol_details']['uri']

it should be I think
services['predix-event-hub'][0]['credentials']['publish']['protocol_details'][0]['uri']
