Change in_Config Parameter at TRIGGERS

[robert.becksteiner]

Hello,
I would like to change a variable from the config-file of an robot when it is triggered.
Is it possible to change a variable from the config file or to I have to change the variable in the excel an publish the robot again?
At Triggers in the orchestrator in the Tab Parameters it is showing Dictionary<String,Object> in_Config. > After clicking on edit I am trying to add the value { “SystemName”, “[Public]” }
I am not able to save it because the error is showing up “a valid JSON must be provided.”
I tried a lot of combinations but nothing is working. What is expacted here?

Am I on the right way?

Hello,
I found it out. It was a formating error: Correct json format is:
{
“Key”: “Value”
}
etc.:
{
“Name”: “APITest”,
“InputArguments”: “{}”,
“Enabled”: true,
“UseCalendar”: false,
“TimeZoneId”: “UTC”,
“StartStrategy”: 2,
“StopProcessDate”: null,
“ExternalJobKey”: “”,
“JobPriority”: null
}
