Failed to execute accumulator server in Orion

I would like to create the subscription using Docker(http://fiware-orion.readthedocs.io/en/develop/user/walkthrough_apiv2/#subscriptions).

However, the accumulator-server.py returned typeerror as bellow:

scripts]# ./accumulator-server.py --port 1028 --url /accumulate --host ::1 --pretty-print -v
verbose mode is on
port: 1028
host: ::1
server_url: /accumulate
pretty: True
https: False
Traceback (most recent call last):
  File "./accumulator-server.py", line 142, in <module>
    print "key file: " + key_file
TypeError: cannot concatenate 'str' and 'NoneType' objects

How can I execute it or create subscription without accumulator-server.py?

Hi! Accumulator server was fixed (see changes in master branch: https://github.com/telefonicaid/fiwar...).

Accumulator-serve.py is a test script for developers to test the context-broker, so you don't need it to run it and create subscriptions.

To start the accumulator server (for testing purpose, as arigliano said) add something like "--key none --cert none" to your command line. Seems there is a bug in the script which requires this values to be defined even if https in not enabled.
