How to pass mixed parameters for an AWS Step Functions state machine

As the error message implies, the string you pass to s3path.$ is not valid JSONPath. If you want to pass some static value, you need to name it without .$ at the end (simply s3path), otherwise, like in your case, it will be treated and validated as a JSONPath.
Static params don't support any kind of string expansion to my knowledge, especially involving JSONPath. I would suggest passing param called s3BucketName in addition to year, month and day, and then simply construct S3 URL inside lambda function itself.

QUESTION

Why use a constructor over protected variables?

Asked 2021-Jun-12 at 04:32

I'm building some classes within unity to define the mechanics individually, and transition between each for easier and cleaner code.

What I wanna know, is when should I be using a constructor to pass variables around, and when to use protected variables. What are the pros and cons of each, and what should I know about them? Also what should I lean towards, like what's practical?

Previously I'd pass these variables into the PlayerState constructor, then in my classes that extend from my PlayerState would follow suit. But if they're protected variables I don't need to pass them into the constructor to access them, and I was wondering what should I do? using UnityEngine;

The new way I'm doing it:

This is just a question related to OOP. Unity is not needed to be considered.

A constructor let you create an object instance and initialize the members of the object at the same time. If there are some immutable members (i.e. they will never be changed after construction), you may need to initialize them in constructors, and you may add the keyword readonly to the members. If you don't need to initialize any member with passing parameter(s) when the instance is created, there is no need to have a custom constructor (unless you want to hide the default constructor).

The access modifier protected makes the member accessible only in code in the same class, or in a class that is derived from that class. If you need to access the member in other places, you still need do it via public/internal methods such as setters and getters, or make it public/internal.

In your case, I think a constructor is needed to initialize the members such as player when a PlayerState instance is created.

Mongoose findById returns object but its properties cant be accessed

From the mongoose docs, I have found out that mongoose findById returns a query object. To access the elements, Either the query has to be converted to a JS object using .toObject(), or the individual properties can be accessed using .get('PROPERTY_NAME').

AWS StepFunctions... Template error: instance of Fn::Sub references invalid resource attribute

Asked 2021-May-17 at 19:54

I am using AWS Lambda within a StepFunctions state machine.

The template below worked fine until I had to change the name of the LogToDatabase function.

Now the Publish to AWS wizard in VS2019 gives this error:

Failed to create CloudFormation change set: Template error: instance of Fn::Sub references invalid resource attribute LogToDatabase.Arn

Any ideas?

Here's my StepFunctions state machine:

ANSWER

Answered 2021-May-17 at 19:54

You just need to change ${LogToDatabase.Arn} to ${LogToDatabaseTask.Arn}. The logical ID of the lambda function is LogToDatabaseTask.

Stateless library - PermitIf usage with SetTriggerParameters

Asked 2021-May-17 at 06:12

How do I use PermitIf with SetTriggerParameters?

In this example I'm modelling a motor, which can go forward, backwards, or off (not moving). Forwards and backwards can be a double speed, so therefore I need SetTriggerParameters. Setting the speed to 0, however, turns the motor off.

I wish to disallow being able to trigger TurnOnForwards or TurnOnBackwards with an argument of 0 - I want the TurnOff trigger to be explicitly the way to turn the motor off. Otherwise, you arrive at the situation where the current state is Forwards/Backwards but with a speed of 0.

This is the error I get:

CS1503 Argument 1: cannot convert from 'UserQuery.Triggers' to 'Stateless.StateMachine.TriggerWithParameters'

Are you exporting the data in './stringToParts' correctly?

When you require a module like './stringToParts', it must be exported. Check if you have something like this at the end of your './stringToParts' file:

Given that you invoke the step function with an object (let's call that A), then a task's...

...InputPath specifies what part of A is handed to your task
...ResultPath specifies where in A to put the result of the task
...OutputPath specifies what part of A to hand over to the next state

So you are currently overwriting all content in A with the result of your Worker state (implicitly). If you want to discard the result of your Worker state, you have to specify:

How do I centralize reused custom Python functions in AWS SAM?

Asked 2021-May-01 at 01:59

I've created a AWS Cloudformation Stack with a template.yaml file that implements several lambda functions. There are several Python functions that some/all of the lambda functions use. Is there a place that I can store common functions? If you think the answer involves layers please address how to include and use custom functions (since the main workflow for layers supports the usual pip python site-package - I'm curious about reusing my own functions).

ANSWER

Answered 2021-May-01 at 01:59

You can publish your python libraries internally to pypi repository and add those to the requirements.txt for the functions. Also ensure your pypi repository proxies any other external libraries you define in the requirements.txt. This may be a bit complicated if you already don't have an internal pypi repository.

Or you can use a Lambda Layer. Let's look at a simple example for using Layers for Python.

Let's say the folder structure of the layer you want to create is where mylib1 and mylib2 are 2 directories which contains some python code. Also you have some third-party dependencies for the code in mylib1/mylib2 or the code in your Lambda function which is defined in the requirements.txt file.
