Hi,

In my test script I try to process 100 lines data from csv data feed via “private val scn = scenario(“test\_scn”).feed(insertFeeder, 100).exec(httpReq)”. But I always get an error “[ERROR] HttpRequestAction - ‘httpRequest-1’ failed to execute: No attribute named ‘name’ is defined”.

Could you please help me to find out the root cause? thank you.

Here is the script:

private val insertFeeder = csv(“test\_data.csv”).queue  
private val csvHeader = GeneralUtil.readFirstLine("“test\_data.csv”")

private val httpConf = http  
.baseURL(“[http://serviceURL](http://serviceURL)”)  
.disableFollowRedirect  
.disableWarmUp  
.shareConnections

/\* Prepare http request \*/  
private var httpReq = http(“insert\_request”)  
.post("/insert")

for (i ← 0 to 99) {  
val paramsInArray = csvHeader.split(",")  
for (param ← paramsInArray) {  
if (param.equalsIgnoreCase(“name”)) {  
httpReq = httpReq.formParam((“name” + “[” + i +"]").el[String] , “${name}”)  
}  
if (param.equalsIgnoreCase(“url”)) {  
httpReq = httpReq.formParam((“url” + “[” + i +"]").el[String] , “${url}”)  
}

if (!param.equalsIgnoreCase(“name”) && !param.equalsIgnoreCase(“url”)) {  
val firstArg = param + “[” + i + “]”  
val secondArg = “${” + param + “}”  
httpReq = httpReq.formParam(firstArg, secondArg)  
}  
}  
}

private val scn = scenario(“test\_scn”)  
.feed(insertFeeder, 100)  
.exec(httpReq)

setUp(  
scn.inject(  
constantUsersPerSec(1) during (1200 seconds)  
).protocols(httpConf)  
).assertions(global.failedRequests.count.lte(5))

And the data in test\_data.csv is:  
name,url,price,size,gender  
image\_1,http://image\_1\_url,100,xl,male  
image\_2,http://image\_2\_url,90,m,female  
image\_3,http://image\_3\_url,10,s,female  
…  
image\_2000,http://image\_2000\_url,200,xl,male

By the way, if I process only 1 line, it works well.

Thank you. I noticed “attribute names, will be suffixed”.
