clasp | clasp Common Lisp environment | Compiler library

EDIT1:I made a minimum reproduction repository here
code & reproduction steps are available at the repository.
EDIT2: Same error occurs when I embeded the transpiled code on html file.

EDIT3: I tracked down the main cause of this problem.
When I use gas-webpack-plugin, output file pukes this error. Simply removing the plugin solves the problem, but then I cannot access my main function on GAS.
I created a github issue on the official gas-webpack-plugin . Hope there's a workaround for this.

---Original question from here---

I'm using Clasp + Typescript + Webpack + Babel to locally develop GAS with npm libraries.
Until I used decorator in my project, it was working fine. However, using decorator(more precisely, class-validator) results in following error on GAS...

I work on a lot of google scripts that are tied to different people's google sheets. Recently I've been trying to shift to using Clasp and VS Code to make it easier to keep a history and add to Github. This is great as it helps streamline my process however, most of the GAS I am working are tied to sheets that are used for someone else's business, which means if I push buggy code, I can mess up their business.

I don't want to push directly to the "production script" without testing the code first using the dummy sheet I built along with my dummy calendar and dummy email. This means that I first want to push the code to my "dummy script", test it, then, when ready, push the code to the "production sheet.

Is there a way to do this? I have looked, but no one seems to have a similar need to my own as most people use clasp to push scripts, then deploy them after testing. My need is different since, when I push the code, it will be effective immediately and does not deploy. Any help on this issue would be appreciated.

I'm using clasp to develop google app scripts projects with Visual Studio Code under various google accounts. So whenever I switch project to work on, I might need to logout from the current account - clasp logout ,and clasp login in to another account.

Is there a way to check what is the current account clasp is logged in?

I have several hundred Google Apps Script projects and have a variety of Bash scripts for managing the projects using the clasp tool (a Node.js app). Many of the scripts require using clasp pull to first pull the projects locally before taking some actions on the local files, so I have a script which loops through local clasp project folders and runs clasp pull on each. The loop iterates through directories sequentially so if it takes 3-4 seconds to pull a project, it ends up taking 5-6 minutes to run it per 100 projects.

My goal is to be able to run the clasp pull commands in parallel so that they all start at the same time, and to be able to know which projects were successfully pulled vs which projects failed to be pulled.

Given a directory structure like this:

I have data such as this:

I have a Google sheet with some code in a bound Apps Script. The code contains some functions that are used in a nightly trigger, and some custom functions used in sheet formulas.

I'm trying to have a sane development process for this, and to decouple saving code from releasing it - so I have a "production" deployment, and the trigger runs code from that deployment - when the code is ready, I update the production deployment with the new version (I use clasp to manage this process). This works fine.

However, I don't know which deployment of my Apps Script code does Google Sheets use when running custom functions? Does it always use code from the @HEAD deployment? Is there a way to control this?

I continuously get an error when going onto the page listed as code here. I have tried undoing changes and nothing seems to be working for me. The error says: "Error: Objects are not valid as a React child (found: object with keys {id, name, published_at, created_at, updated_at}). If you meant to render a collection of children, use an array instead.

I have a word game here made with javascript,

I play against a robot that guesses a word from a directory of words it has. If the guessed word have a matching letter and matching index it turns blue and gets displayed.

If any letter only exist in the guess word but not at correct index it turns orange.

The robot now randomly guesses the words and doesn't do anything with the blue or orange letters. I want the robot to filter the word directory it guesses from with the letters that are correct or exist in the guess word.

I can store those letters in two variable but I'm having scope problems to filter the word directory from the scope these variable
