Hi,

i want to install the WS EMS on my Raspberry Pi.

 

When I execute wsems, following error occurs:

~/microserver % sudo ./wsems

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!

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:
