RequestContext initialization failed in cinder.

[huangtianhua]

RequestContext initialization failed in cinder because of the following error:
                   "TypeError: 'in <string>' requires string as left operand, not NoneType"

My operations as follows:

1.Call keystone api to create a service without type.
2.Call keystone api to add a endpoint with the service.
3.Call cinder api to list servers.

Then the error TypeError: 'in <string>' requires string as left operand, not NoneType" has been thrown.
