**APM Agent language and version** : Java 1.43.0 **Description of the problem including expected versus actual behavior.** After upgrading the AWS SDK v2 in our spring boot service from 2.20.162 to 2.21.0 we see the following message during startup that did not happen before: ```auto 2023-10-18 06:26:05,586 [main] WARN co.elastic.apm.agent.bci.bytebuddy.ErrorLoggingListener - Error on transformation software.amazon.awssdk.core.internal.handler.BaseAsyncClientHandler java.lang.IllegalStateException: Cannot locate field named clientConfiguration for class software.amazon.awssdk.core.internal.handler.BaseAsyncClientHandler at net.bytebuddy.asm.Advice$OffsetMapping$ForField$Unresolved.resolve(Advice.java:2556) ~[elastic-apm-agent-40510175845988f13f6162ed8526f0b0-a9910a9589b2cceb9a41936e297bb41c.jar:1.43.0] at net.bytebuddy.asm.Advice$OffsetMapping$ForField.resolve(Advice.java:2481) ~[elastic-apm-agent-40510175845988f13f6162ed8526f0b0-a9910a9589b2cceb9a41936e297bb41c.jar:1.43.0] ... ``` As a consequence, traces that contain communication over SQS stop after an SQS message was sent and the spans after receiving the message are missing. **Steps to reproduce** 1. Start a spring boot service that uses the APM Java agent 1.43.0 and the AWS Java SDK 2.20.162 2. Trigger a transaction that sends a message via SQS to another service with the same dependency versions 3. Check the corresponding trace in Kibana **Expected behavior** No error message on startup. Traces continue after SQS message is received. **Actual behavior** Error at service startup. Received SQS messages are not visible in their corresponding trace. **Addtional information** I think the relevant change in the AWS Java SDK is this > > > \* Request level plugin execution > > \* Update PR after internaly sync up about th…e approach > > \* Update PR after internaly sync up about the approach > > \* Fix time offset handling Looking at the "Cannot locate field named clientConfiguration" part of the error to me it seems the root cause is that `clientConfiguration` has been removed from the derived class and only exists on the base class now where it's private. Edit 2024-05-16: somehow this topic got flagged as spam?!? Editing it to unhide it... ---

> [@IngoStrauch2020](#): > > 2.21.0 Hi @IngoStrauch2020 , Yes, indeed, there have been changes in the new version of the aws sdk. Today I will send a hotfix to solve this problem. ---

The PR got merged about a month ago but it seems there was no release since then. Do you have an estimate when the next version will come? ---
