Cannot invoke Lambda AWS on java locally

Question

I run the following commands:

1) sls create --template aws-java-maven
2) mvn clean install
3) sls invoke local -f hello

I got this error:

Serverless: In order to get human-readable output, please implement "toString()" method of your "ApiGatewayResponse" object.

Adding both log4j and log4j2 with version 1.0.0 (decreased from 1.1.0) helped ...

<dependency>
  <groupId>com.amazonaws</groupId>
  <artifactId>aws-lambda-java-log4j</artifactId>
  <version>1.0.0</version>
</dependency>
<dependency>
  <groupId>com.amazonaws</groupId>
  <artifactId>aws-lambda-java-log4j2</artifactId>
  <version>1.0.0</version>
</dependency>

Why not to accept the answer from @JunedAhsan instead of copy pasting his answer?

Will Graham Over a year ago

@nickolay.laptev that answer didn't help, it doesn't work with version 1.1.0, only with 1.0.0 for log4j and log4j2

It seems you are missing some runtime logger dependencies. Try adding these to your pom file

<dependency>
  <groupId>com.amazonaws</groupId>
  <artifactId>aws-lambda-java-log4j2</artifactId>
  <version>1.1.0</version>
</dependency>

Also, you need to make sure that you are using the compatible version of Java AWS SDK, which is generally the same version number.Something like this

<dependency>
  <groupId>com.amazonaws</groupId>
  <artifactId>aws-lambda-java-log4j</artifactId>
  <version>1.0.0</version>
</dependency>

This also work for me....

 <dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-lambda-java-log4j2</artifactId>
     <version>1.1.0</version>
 </dependency>

In java file add below lines.

LambdaLogger logger = context.getLogger();

logger.log("received: " +input.toString());
