yes we had followed the same link and used AWS_LAMBDA_EXEC_WRAPPER.
We use node-postgres to execute DB calls.
Note : We are not using extensions for now. We use https://www.npmjs.com/package/@dynatrace/oneagent to integrate dynatrace with our Lambdas written in nodejs which works fine. Need help to integrate dynatrace for Java based lambdas.
We had tried extensions but database calls were not traced. We are using PostgreSql and Dynatrace support team confirmed that its driver is not yet supported in the Extensions. We had dropped the plan of using Extensions.
We have managed to integrate Dynatrace with NodeJs lambdas using OA npm module. Need help for a Lambda which is written in Java.
