Context

When executing a function with zappa.async.run in a non lambda environment an error is raised. This seems to happen due to the fact that zappa tries to run the function in the lambda environment even if it's not in the lambda environment. When using the @task decorator this works as expected since there is a direct invokation of the function if AWS_LAMBDA_FUNCTION_NAME env variable is not present.

Expected Behavior

The function should be invoked directly, without errors, in a non lambda environment.

Actual Behavior

The function fails with error

Invalid type for parameter FunctionName, value: None, type: <class 'NoneType'>, valid types: <class 'str'>

Possible Fix

Change this code:

to
(copied from @task decorator)

if (service in ASYNC_CLASSES) and (lambda_function_name):
  send_result = ASYNC_CLASSES[service](lambda_function_name=lambda_function_name,
                                                     aws_region=aws_region,
                                                     capture_response=capture_response).send(task_path, args, kwargs)
   return send_result
else: #  For local exexution
  return func(*args, **kwargs)
