Expected

contains

• functionName
• functionVersion
• functionArn

etc.

Am I missing something ?

Hi, thanks for your message. I've just tried with the example and I have the function information:

{
    "timestamp": "2023-06-28T07:34:21.824+0000UTC",
    "instant": {
        "epochSecond": 1687937661,

    "level": "INFO",

    "loggerFqcn": "org.apache.logging.log4j.spi.AbstractLogger",
    "threadId": 1,
    "threadPriority": 5,
    "coldStart": "true",
    "functionArn": "arn:aws:lambda:eu-west-2:705456458224:function:powertools-core-HelloWorldFunction-JkgcEOm8TW1M",

}

Nothing jumps to my eyes with what you're sharing, I suspect you don't have the proper aspectJ configuration in your gradle:

plugins{
    id 'java'
    id 'io.freefair.aspectj.post-compile-weaving' version '6.3.0'
}

repositories {
    mavenCentral()
}

dependencies {
    aspect 'software.amazon.lambda:powertools-logging:1.15.0'
}

sourceCompatibility = 11
targetCompatibility = 11

@jeromevdl

Thank you for the solution !
As you told me, @Logging is enabled by setting to aspect.

[jeromevdl]

Thanks, good to see it worked.
