Hello, I have been following the below article for load testing with AWS SQS: [https://gatling.io/2019/01/load-testing-aws-sqs-with-gatling/](https://gatling.io/2019/01/load-testing-aws-sqs-with-gatling/) The example uses the textMessage method for sending a message. For my use case, I will need to send a nested map to SQS which will then be taken by an application. I tried using the mapMessage method but it seems to fail with: 17:08:19.253 [GatlingSystem-akka.actor.default-dispatcher-9][ERROR][Action.scala:71] i.g.j.a.Send - ‘jmsSend-2’ crashed with ‘j.j.JMSException: Unsupported Method’, forwarding to the next one I even tried sending the following: mapMessage(“foo” → “bar”). That failed as well. Any help would be highly appreciated! gatling version: 3.0.3 ---

First thing first, Gatling 3.0.3 is very old. Please upgrade to a modern maintained version (latest is 3.6.1) so people can try to help you. ---

Thanks for the quick reply. I checked the maven repo that was linked below: [https://gatling.io/docs/gatling/reference/current/extensions/maven\_plugin/](https://gatling.io/docs/gatling/reference/current/extensions/maven_plugin/) Seems like the latest is 3.1.2. I did update to that but I still run into the issue. Thanks, Karthik ---

Thanks for getting back to me! I did take a look at the maven repo and it seems 3.1.2 is the latest over there. [https://gatling.io/docs/gatling/reference/current/extensions/maven\_plugin/](https://gatling.io/docs/gatling/reference/current/extensions/maven_plugin/) I did upgrade to that but I still run into this issue. Thanks, Karthik ---

Versions of the maven plugin and of Gatling itself are not related. ---

Then, it simply seems the SQS JMS adapter doesn’t support Map messages. ---

Thanks for getting back to me Stephane! I do see that on the documentation for jms on gatling, it does mention that mapMessage is supported. [https://gatling.io/docs/gatling/reference/current/jms/#message](https://gatling.io/docs/gatling/reference/current/jms/#message) Also, in the what’s new section of 3.1, there is section that mentions added support for mapMessage. [https://gatling.io/docs/gatling/reference/current/whats\_new/3.1/](https://gatling.io/docs/gatling/reference/current/whats_new/3.1/) So, just to clarify, does SQS JMS Adapter not support mapMessages then? Thanks, Karthik ---
