Netty Exceptions during PUT Simulation

Gatling (Open-Source)
1

Hi,

Due to some critical project deadlines I have not yet got a chance to explore/migrate RC1.
So this is with M3a on which we had developed elaborate suite

I’m trying to performance test a REST PUT API (xml request payload) which returns 204, and empty response body on success and some information in the reponse header.
I’m getting below error when I run the simulation.

I have tried TRACEing out the HTTP request/response , and when I used the exact parameters as I see in Gatling trace in a REST client like POSTMAN it works all good.
But it is failing with when I run from Gatling with below trace, which seems ,more like Gatling bug.

I have tested and verified the code in detail. It looks good.

Is there some known issue with Netty ? Thank you advance for any suggestions to mitigate the problem!

Regards

shree

I ported the same to RC1, I get the similar runtime error on Netty
Note that tests for GET and POST versions of the API are successful

You probably mixed some jars and deps from 2M3 and RC1.
You probably have several async-http-client jars in your classpath.
