Issue: Trying to emit before Angular Webpack plugin has been initialized (Error: Emit attempted before Angular Webpack plugin initialization)

Currently, I am working on a project in Angular 15 where I am migrating code from Angular version 5. Despite fixing all the errors, I'm facing one particular issue. Here are the details of my current Angular version:

Angular CLI: 15.2.10 Node: 18.18.2 Package Manager: npm 10.2.0 OS : win32 x64

The error I'm encountering is as follows: [Error]: https://i.sstatic.net/22xkl.png

Below is my package.json file:

{
  "name": "demo",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "prod": "node --max_old_space_size=4096 node_modules/@angular/cli/bin/ng build --prod",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e",
    "build-prod": "node --max_old_space_size=5048 ./node_modules/@angular/cli/bin/ng build -- prod"
  },
  "private": true,
  "dependencies": {
    "@agm/core": "^1.0.0-beta.3",
    "@angular/animations": "^15.0.0",
    "@angular/common": "^15.0.0",

  },

    "@angular/cli": "^15.2.10",
    "@angular/compiler-cli": "^15.0.0",
    ...
  }
}

Here is angular.json file:

{
  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
  "version": 1,
  "newProjectRoot": "projects",
  "projects": {
    "demo": {

    }
  },
  "cli": {
    "analytics": "125d0ec8-f37c-4580-834c-591ee3bb8c6c"
  }
}
Here is tsconfig.json

Hey there, I recommend taking the following actions. Based on my understanding, you are attempting to transition from angular version 5 to angular version 15 using ng update, however this may not be the most practical approach. Instead, consider the steps outlined below:

  1. Start by creating a new angular app with angular version 15
  2. Make sure to back up your current project code while keeping the node modules intact
  3. Replace the src folder, integrate all third-party dependencies into package.json, and incorporate any scripts or styles from the existing project into the newly created angular project
  4. Proceed to run 'npm i'
  5. If you encounter any compatibility issues with third-party dependencies, try updating them before rerunning 'npm i'

It is not advisable to keep angular 5 for an extended period of time; aim to update your angular version every one to two years.

I trust that these steps will assist you in your endeavors. Wishing you safe coding practices and success in your projects.
