> +Question:+
> Failed to execute accumulator server in Orion
> +Description:+
> Hello,
> 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?
