Unexpected error occurred when using powertools in lambda function about powertools-lambda-java HOT 6 CLOSED

As a side note, removing org.apache.logging.log4j:log4j-slf4j-impl from the dependencies suppress the error, but then there's a timeout in Transforming org/apache/logging/log4j/core/lookup/JndiLookup (lambdainternal.CustomerClassLoader@76fb509a)

Hey @trourance thanks for raising the issue!
Do you mind including:

• Some info / code about your logging setup
• The logging deps you are carrying and their versions

It looks like you are missing some part of slf4j needed to hook into log4j. We support log4j primarily in our current setup, so I'd guess that piece in the middle is involved.

@trourance do you mind quickly chucking this dependency in instead of log4j-slf4j-impl ?

https://mvnrepository.com/artifact/org.apache.logging.log4j/log4j-slf4j2-impl

from powertools-lambda-java.

@scottgerring In the lambda, we only use only one logger, the context logger, e.g. context.logger.log(...).
In the rest of our code, we use only org.apache.logging.log4j:log4j-core:2.17.2, instantiated with LogManager, e.g. val log = LogManager.getLogger(...)

@scottgerring Using log4j-slf4j2-impl instead of log4j-slf4j-impl fixed that issue, thanks for pinpointing the mistake !

No worries @trourance glad to help 🙇
