The sources field in the generated sourceMap is always ["sourceMap"]

I obfuscate my code use config

{
    compact: true,
    controlFlowFlattening: true,
    controlFlowFlatteningThreshold: 1,
    debugProtection: false,
    debugProtectionInterval: false,
    disableConsoleOutput: false,
    identifierNamesGenerator: 'hexadecimal',
    log: true,
    renameGlobals: false,
    rotateStringArray: true,
    selfDefending: true,
    stringArray: true,
    stringArrayEncoding: 'rc4',
    stringArrayThreshold: 1,
    transformObjectKeys: true,
    unicodeEscapeSequence: false,
    sourceMap: true,
    sourceMapMode: 'inline',
}

after I decode the base64 encoded sourceMap, I found “sources”:[“sourceMap”], this made all the error stack shows the correct line number with wrong filename ''sourceMap"

Expected Behavior

the error stack from a file a.js should have error stack with filename a.js

Current Behavior

the error stack from a file a.js have error stack with filename sourceMap.js

Steps to Reproduce (for bugs)

1. create a file ‘a.js’
2. the first line of ‘a.js’ should require('source-map-support').install();.
3. throw error in ‘a.js’, use console.log() print the error stack
4. do obfuscate with the config above
5. run the obfuscated a.js
6. the error stack show the bug

Your Environment

• Version used: node: 8.10.0 javascript-obfuscator: latest

Stack trace

Minimal working example that will help to reproduce issue

Obfuscator has two interfaces: CLI and Node API.

With CLI - obfuscator reads file and know file name of this file. With CLI obfuscator passing internallyinputFileName based on name of the input file, and as result - you wont to do this manually. inputFileName is not available with CLI.

With Node API (all plugins are using this variant) obfuscator knows nothing about files. It obfuscating strings with source code and you should pass inputFileName value, so obfuscator will know name of the file that contains source code.

Fix in master branch now. Until release you can use version from master branch.

When 0.17.0 will released, you have two options:

• wait until author of plugin manually added passthrough of input file name to the inputFileName option
• manually add input file name as value of inputFileName option.
