SAM local api - VSCode launch.json - Debugger not starting

[SilvioSilvaCvT]

Description:

I'm trying to start an APIUnable to start/attach to the debugger on VSCode.

Steps to reproduce:

Run VSCode debugger:

With the folowing config:

    "version": "0.2.0",
    "configurations": [
        {
            "debugServer": 60000,
            "type": "aws-sam",
            "request": "direct-invoke",
            "name": "AWS-SAM",
            "invokeTarget": {
                "target": "api",
                "templatePath": "template.yaml",
                "logicalId": "LambdaFunctionApp"
            },
            "api": {
                "httpMethod": "get",
                "path": "/test",
            },
            "sam": {
                "localArguments": [
                    "--debug",
                    "--debugger-path",
                    "/tmp",
                    "--debug-function",
                    "LambdaFunctionApp",
                    "--debug-port",
                    "60000",
                    "--warm-containers",
                    "EAGER"
                ]
            },
            "aws": {}
        }
    ]
}

Observed result:
