[Question] How can I test the lambda?

I am, not just unit testing, but the app itself. When I try to run it I get the error:

```
Unhandled exception:
NoSuchMethodError: The getter 'requestId' was called on null.
Receiver: null
Tried calling: requestId
#0 Object.noSuchMethod (dart:core-patch/object_patch.dart:51:5)
#1 Runtime.invoke (package:aws_lambda_dart_runtime/runtime/runtime.dart:117:28)

#2 main (file:///C:/Users/shina/Desenvolvimento/dart_projects/lambda_test/bin/lambda_test.dart:62:7)
#3 _startIsolate. (dart:isolate-patch/isolate_patch.dart:301:19)
#4 _RawReceivePortImpl._handleMessage (dart:isolate-patch/isolate_patch.dart:168:12)
```

There is a way to run it (for testing purposes) locally, without having to upload the zip file to aws?
