Error: stringArrayEncoding's elements must be unique

[communque]

Trying to obfuscate some code, and I got an error I haven't encountered yet: stringArrayEncoding's elements must be unique

The code was retrieved from a postgreSQL database with utf-8 encoding stored in memory.

Machine being used: CentOS Linux release 7.9.2009 (Core) require("javascript-obfuscator") returns [class s] { version: '2.10.1' }

The same JS Code obfuscated on a MacOS v11.1 where require("javascript-obfuscator") returns [class a] { version: '0.27.4' } works just fine with no errors.

What might account for this? What possible solutions?

Code and errors listed below:

JsObfOptions={
    compact: true,
    controlFlowFlattening: true,
    controlFlowFlatteningThreshold: 0.75,
    deadCodeInjection: true,
    deadCodeInjectionThreshold: 0.4,
    debugProtection: false,
    debugProtectionInterval: false,
    disableConsoleOutput: true,
    identifierNamesGenerator: 'hexadecimal',
    log: false,
    renameGlobals: false,
    rotateStringArray: true,

    stringArray: true,
    stringArrayEncoding: 'base64',
    stringArrayThreshold: 0.75,
    transformObjectKeys: true,
    unicodeEscapeSequence: false
}

JsCodeObf=require("javascript-obfuscator").obfuscate(JsCodeClean, JsObfOptions);

Resolved: In the JsObfOptions JSON, changed stringArrayEncoding to ['none', 'base64', 'rc4']

Hi. Yes, stringArrayEncoding option should be an array with encodings
