Hi,
i want to install the WS EMS on my Raspberry Pi.
When I execute wsems, following error occurs:
~/microserver % sudo ./wsems [FORCE] 2018-09-05 08:51:01,119 ./wsems: Initializing EMS ....

This is my config file:
{ "ws_servers": [{ "host": "192.168.100.164", "port": 443 }], "appKey": "********-****-****-****-************", "http_server": { "use_default_certificate" : true, "ssl" : true, "authenticate" : false }, "certificates": { "validate": false, "allow_self_signed": true }, "ws_connection": { "encryption": "none", "verbose": false } }
Does anyone know how i could fix this problem?
Thanks!
Solved! Go to Solution.
You are required to have a logger config section:
"logger": {
"level":"DEBUG"
},
I was able to reproduce the :
[ERROR] 2018-09-05 13:08:40,458 SDK: twMap_Add: parse function returned null.
when I removed the logger configuration. You can set to INFO if you want less output
The http_server section of the EMS config file is for the local server that the EMS starts - not the EMS connection to the ThingWorx Server.
The ws_connection section controls the EMS connection to the ThingWorx server. Try this:
"http_server": {
"ssl": false,
"authenticate": false
},
"ws_connection": {
"encryption": "ssl"
}
Thanks for your reply.
Unfortunately I still get an error:

My config file:
{ "ws_servers": [{ "host": "192.168.100.164", "port": 443 }], "appKey": "d9c999e1-c645-4e25-9f77-d3d49cfeb2c1", "http_server": { "ssl" : false, "authenticate" : false }, "certificates": { "validate": false, "allow_self_signed": true }, "ws_connection": { "encryption": "ssl" } }
What am I doing wrong?

Thank you! The error still appears but it looks like the server is connected now
