Hi,

I tried to follow the documentation ([https://gatling.io/docs/2.3/http/polling/](https://gatling.io/docs/2.3/http/polling/)) to start polling a REST call and my code is:

**exec(**  
**polling**  
**.every(2 seconds)**  
**.exec(http(“Home”)**  
**.get("/iPIM/rest/api/jobhistory/search?running=true")**  
**.headers(rest\_headers)**  
**.check(bodyString.saveAs(“restResponse”))**  
**))**

but I get an exception that nothing is called during simulation:

**Exception in thread “main” java.lang.UnsupportedOperationException: There were no requests sent during the simulation, reports won’t be generated**

Any ideas?

Thanks
