AWS Lambda Handler Severless Invoke local : Class Not found

Hey Guys,

So I've been struggling on this since two weeks now ....

So i'm trying to make my handler encrypt some file and return me a string, the encrypt function just return a base64 string the one i want:

`public class Handler implements RequestHandler<Map<String, String>, String>{

@Override
public String handleRequest(Map<String, String> input, Context context) {
	context.getLogger().log("Input: " + input);
	
	Response rep = new Response(input);
	
	String output = "File: " ;
	String temp = rep.getType();
	
	if(temp.equals("pdf")) {
		
		output += Encrypt.encryptPDF(rep.getFile(), rep.getUserPwd(), rep.getOwnerPwd());
	}
	if(temp.equals("xlsx")) {
		output += Encrypt.encryptXLSX(rep.getFile(), rep.getPassword(), rep.getFilename());
	}
	if(temp.equals("zip")) {
		output += "OK";
	}
	
	return output;
}

}`

Here is my description of the handler on serverless.yml:

functions: encrypt: handler: com.spinifexit.file.security.aws.Handler::handleRequest

And My issue when i try to invoke it on local:

`sls invoke local --function encrypt

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

java.lang.ClassNotFoundException: com.spinifexit.file.security.aws.Handler

For now i'm not passing data yet but i already tried with some still the same.

My Environment:
-AWS Java SDK lambda v1.11.546
-AWS lambda java core v1.2.0
-JDK v1.8.0_211

Thanks :)

Start with serverless.yml and reproduce the failure using sls invoke local --function encrypt, then trace how the Java handler class is packaged and loaded for local invocation. Done means the configured com.spinifexit.file.security.aws.Handler class is found and the encrypt function can be invoked locally.
