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
