webpack-obfuscator not working on Firebase deployment

[bangank36]

Expected Behavior

webpack-obfuscator and javacript-obfuscator should be working on Firebase deployment without issue

Current Behavior

My firebase functions are deployed correctly unless I import webpack-obfuscator or javacript-obfuscator
Always produce error

Did you list all required modules in the package.json dependencies?
Detailed stack trace: Error: Cannot find module 'webpack-obfuscator'

	webpack-obfuscator	javacript-obfuscator
sample code
error

Steps to Reproduce

• Install webpack-obfuscator
• Run firebase emulators:start to test the function, it working properly
• Run firebase deploy the functions can not be deployed

Enviroment

• Node 14
• "webpack-obfuscator": "3.5.1",
• "javascript-obfuscator": "4.0.2"

Reference

I have taken a look at these issues, but either they are outdated or not work

• deadCodeInjection and stringArray cause error "Cannot find module" in Electron javascript-obfuscator#687
• Test loader doesn't work : Critical dependency: the request of a dependency is an expression #138
• Error: Cannot find module 'webpack-obfuscator/loader' #82 (comment)

cc: @sanex3339 since you found a bug in loader ( but it was 3 years ago )

• While I can not figure out the root cause of this issue. I have come up with a work around by import the webpack-obfuscator on runtime, doing that making the Firebase deployment works seamlessly

Before

const StringReplacePlugin = require("string-replace-webpack-plugin");
const TerserPlugin = require('terser-webpack-plugin');
const WebpackObfuscator = require('webpack-obfuscator');

module.exports = function(inputFile, siteId, WebpackObfuscator) { ... }

After

const StringReplacePlugin = require("string-replace-webpack-plugin");
const TerserPlugin = require('terser-webpack-plugin');

module.exports = function(inputFile, siteId, WebpackObfuscator) { 
    const WebpackObfuscator = require('webpack-obfuscator');
    ....
}
