Hello,

While trying to connect my Raspberry 3 B+ to Platform, i get this error when doing : sudo ./luaScriptResource :

[FORCE] 2020-09-26 14:10:45,205 ./luaScriptResource: Starting up ....

Myabe something wrong in my config ?

config.lua

scripts.log_level = "INFO"
scripts.script_resource_ssl = false
scripts.script_resources_authenticate = false
scripts.PiThing = {
 file = "thing.lua",
 template = "PiTemplate",
 scanRate = 1000,
 taskRate = 30000
 }
scripts.rap_host = "127.0.0.1"
scripts.rap_port = 8080



scripts.data_security_key_hash="4vt6VnYj+93wOHypT0jFoIwvk93bsM3UA7n1WAS7FqQ"

config.json

{
 "ws_servers": [{
 "host": "pp-2009221255A9.devportal.ptc.io",
 "port": 443
 }],
 "appkey": "a814e827-9f06-41a3-bbeb-7b615abbe3df",
 "http_server": {

 "ssl": false,
 "authenticate": false
 },
 "logger": {
 "level": "INFO"
 },
 "certificates": {

 }
}

I'm using Thingworx platform 9.0 Trial

What version of EMS are you using?

The latest version of EMS has changed to disallow default insecure behavior.

Try this config file that explicitly turns off security features:

scripts.log_level = "INFO"
scripts.script_resource_ssl = false
scripts.script_resource_authenticate = false
scripts.script_resource_host = "127.0.0.1"
scripts.script_resource_port = 8001
scripts.PiThing = {
 file = "thing.lua",
 template = "PiTemplate",
 scanRate = 1000,
 taskRate = 30000
}
scripts.rap_host = "127.0.0.1"
scripts.rap_port = 8080
scripts.rap_ssl = false
scripts.rap_server_authenticate = false

Thank you for your answer.

I used your file, i had this error :

[ERROR] 2020-10-01 12:33:38,698 luaConfigurator::initialize: Error while loading file /home/pi/Desktop/microserver/etc/config.lua. msg: /home/pi/Desktop/microse rver/etc/config.lua:5: malformed number near '127.0.0.1'

So i added some " ", it's going better and now i have this one :

Looks like there is still 2 errors, one in PiTemplate and the other one... i have no clue.

I don't know which version of EMS i'm using, and don't know where to find this info (i did search)
