Failed to execute accumulator server in Orion
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?
