java.lang.ArrayIndexOutOfBoundsException: Feeder source is empty

Dear, all!
I stuck with this problem.
When I had pointed
val feeder=csv(“data/sid.csv”).circular
val scn = scenario(“Load Test 1”)
my sid.csv file became empty and I got ava.lang.ArrayIndexOutOfBoundsException: Feeder source is empty error.

What do you mean by


Gatling does not write on your file.
And circular strategy is meant to start at the beginning when the end is reached.

Either you began with an empty file, or the file is not found.

Please provide a full sample.

What is the version you use?


Any chance you’re using an old version and haven’t checked if upgrading to 3.8.3 fixes your issue?

Unfortunately, after upgrading Gatling up to 3.8.3 version the error is still the same.
Process exited with an error: 255 (Exit value: 255)

Then please provide a reproducer as requested here.
Without one, we can’t help and are just shooting in the dark.
