when i debug apm , i found 1.31.0 will no step to co.elastic.apm.agent.bci.ElasticApmAgent#getTransformer, can you give me some suggestions to solve this problem?

You problem might also be resolved by upgrading the elastic-agent to at least 1.34.0. This version contains a change (#2728) which should isolate the elastic agent from any dependencies your custom agent loads. In addition this should save you the overhead of always keeping the dependencies of both in sync.

Hi @LeePui did that resolve the issue?

yes, thanks.
