I am having the exact same issue. What is odd is that in the documentation ( http://docs.openstack.org/trunk/openstack-compute/install/content/keystone-service-endpoint-create.html (http://docs.openstack.org/trunk/opens...) ) they have you use this syntax but just before they create the nova volume endpoint they define "TENANT=" and then enter the endpoint-create command. In their output it looks right but I think the variable should have been defined early perhaps. I have tried with and without and neither work.

When I try to curl or token-get against Keystone I get either a NO JSON object could be decoded or a "resource not found".

Keystone was running prior to creating these endpoints and now it seems it is dead. Log shows:

(root): 2012-04-27 07:25:01,894 ERROR argument of type 'NoneType' is not iterable Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/keystone/common/wsgi.py", line 184, in __call__ result = method(context, **params) File "/usr/lib/python2.7/dist-packages/keystone/service.py", line 249, in authenticate if 'passwordCredentials' in auth: TypeError: argument of type 'NoneType' is not iterable

I have the same proble when I follow the openstack-essex 25-04-12 install and deploy manual ( http://docs.openstack.org/trunk/openstack-compute/install/content/ (http://docs.openstack.org/trunk/opens...) ). I get a simialr error when using the curl command:

For me the problem with the using %(tenat_id)s in keystone was due to older version of python (and nova) in the Ubuntu software repositories when I first installed Ubtuntu 12.04 and the openstack software.

This was fixed by:

$ sudo apt-get update $ sudo apt-get dist-upgrade $ sudo apt-get upgrade

Both python and nova were upgraded.

I then entered the service endpoints exactly as shown in http://docs.openstack.org/trunk/openstack-compute/install/content/keystone-service-endpoint-create.html (http://docs.openstack.org/trunk/opens...) , using %(tenant_id)s, e.g: It was not necessary to define $TENANT or substitute tenant_id with code numbers for the 2 service tenant, e.g. $ keystone --token 012345SECRET99TOKEN012345 \ --endpoint http://192.168.206.130:35357/v2.0/ \ endpoint-create \ --region RegionOne \ --service_id=abc0f03c02904c24abdcc3b7910e2eed \ --publicurl='http://192.168.206.130:8774/v2/%(tenant_id)s' \ --internalurl='http://192.168.206.130:8774/v2/%(tenant_id)s' \ --adminurl='http://192.168.206.130:8774/v2/%(tenant_id)s'

After reading through http://www.gossamer-threads.com/lists/openstack/dev/10816 (http://www.gossamer-threads.com/lists...) , I also added the following line in my keystone.conf. Although the template_file line may not be needed.

[catalog] driver = keystone.catalog.backends.sql.Catalog template_file = /etc/keystone/default_catalog.templates

I was then able to see the endpoints for both service tenants using the curl command:

curl -d '{"auth": {"tenantName": "openstackDemo", "passwordCredentials":{"username": "adminUser", "password": "secretword"}}}' -H "Content-type: application/json" http://192.168.206.130:35357/v2.0/tokens | python -mjson.tool Listed the endpoints for the openstsckDemo tenant, with the service tenant id code:

            "endpoints": [
                {
                    "adminURL": "http://192.168.206.130:8774/v2/abcd12345678912345678912345", 
                    "internalURL": "http://192.168.206.130:8774/v2/abcd12345678912345678912345", 
                    "publicURL": "http://192.168.206.130:8774/v2/abcd12345678912345678912345", 
                    "region": "RegionOne"
                }
            ], 
            "endpoints_links": [], 
            "name": "nova", 
            "type": "compute"

$ curl -d '{"auth": {"tenantName": "service", "passwordCredentials":{"username": "nova", "password": "novapasword"}}}' -H "Content-type: application/json" http://192.168.206.130:35357/v2.0/tokens | python -mjson.tool Listed the endpoints for the service tenant, with the service tenant id code:

            "endpoints": [
                {
                    "adminURL": "http://192.168.206.130:8774/v2/efghij12345678912345678912345", 
                    "internalURL": "http://192.168.206.130:8774/v2/efghij12345678912345678912345", 
                    "publicURL": "http://192.168.206.130:8774/v2/efghij12345678912345678912345", 
                    "region": "RegionOne"
                }
            ], 
            "endpoints_links": [], 
            "name": "nova", 
            "type": "compute"
        },

I was then able to authenticate glance add commands wihtout getting an error.

Hi guys, I had a similar problem following the Essex installation instructions available at [1] for creating endpoints, but in the end I realized I had forgotten to add information about the "adminurl" field, thus obtaining the response:

{ "error": { "code": 500, "message": "An unexpected error prevented the server from fulfilling your request. 'NoneType' object has no attribute 'replace'", "title": "Internal Server Error" } }

It is useful, nonetheless, to run nova and other commands using the debug flag to check if you are just forgetting to pass information when registering your endpoints or if your authentication information is invalid.
