Hi,  
I have recorded script with HAR, and have used grouping in the script like,  
val scn = scenario(“Scenario Name”)

.group(“Navigate To URL”){  
exec(http(“request\_0”)  
.get(“sampleUrl.asp”)  
.headers(headers\_0)  
.resources(http(“request\_1”)  
.get(“sampleUrl.js?\_v=4.10.0.17”)  
.headers(headers\_1),  
http(“request\_2”)  
.get(“sampleUrl.js?\_v=4.10.0.17”)  
.headers(headers\_1)}

When i run gatling.bat, following errors are displayed

Can you please try the below code. You seems to be something missing in your code.

object scenario1{  
val scenario1 =  
group(“Navigate To URL”){  
exec(http(“request\_0”)  
.get(“sampleUrl.asp”)  
.headers(headers\_0)  
.resources(http(“request\_1”)  
.get(“sampleUrl.js?\_v=4.10.0.17”)  
.headers(headers\_1),  
http(“request\_2”)  
.get(“sampleUrl.js?\_v=4.10.0.17”)  
.headers(headers\_1)))}  
}

val scn =scenario(“scenario name”){exec(scenario1.scenario1)}

It will group the requests and group name is displayed and expanding the group name will give transaction inside the group .
