When invoking a Lambda from Node.js code.


    const lambda = new Aws.Lambda(creds);
    
    const payload = {};
    
    const clientContext = {
        invokedFunctionArn: this._workerArn
    };
    
    const params = {
        FunctionName: this._workerArn,
        InvocationType: "RequestResponse", // "DryRun",
        LogType: 'Tail', // "None", "Tail"
        ClientContext: JSON.stringify(clientContext),
        Payload: JSON.stringify(payload)
    };
    
    console.log(`DEBUG: Executing lambda ${JSON.stringify(params)}`);
    
    lambda.invoke(params, function (err, data) {
        console.log(`DEBUG: Printing lambda return arguments`);
        console.log(JSON.stringify(arguments));
        console.log(data.LogResult);
    });```
DEBUG: Printing lambda return arguments
{"0":null,"1":{"StatusCode":200,"Payload":"null"}}
undefined
```

Expecting to see the Lambda execution log in `data.LogResult`, but no such object returned,
yet Localstack Cloudwatch logs recorded the execution logs correctly.

What I'm missing? Why it doesn't return logs on invoke?

Thanks
