Hello Stephan,

I am able to use the “group” function in the ChainBuilder, but when I use it in the ScenarioBuilder it is giving an error. Following is the sample code with and without “group” functions. Please help me in fixing it.

-----Without “Group”-----  
private ScenarioBuilder scn = scenario(“gatling”)  
.exec(  
http(“request\_0”)  
.get("/")  
.headers(headers\_0)  
)  
.exec(  
http(“request\_0”)  
.get("/")  
.headers(headers\_0)  
)  
.exec(  
http(“request\_1”)  
.get("/wp-content/plugins/autoptimize/classes/external/js/lazysizes.min.js?ao\_version=2.9.5")  
.headers(headers\_1)  
);

-----With “Group”-----

private ScenarioBuilder scn = scenario(“gatling”)  
.exec(  
http(“request\_0”)  
.get("/")  
.headers(headers\_0)  
)  
.group(“group”).on(  
.exec(  
http(“request\_0”)  
.get("/")  
.headers(headers\_0)  
)  
.exec(  
http(“request\_1”)  
.get("/wp-content/plugins/autoptimize/classes/external/js/lazysizes.min.js?ao\_version=2.9.5")  
.headers(headers\_1)  
));

Regards,  
Bharath.
