Found problem with object key:

    0: <---- webpack generating this, causes error
    "0": <---- if 0 replace to "0" - error gone

Yes, all numeric keys are deleted

var s = {0: 'foo', '1': bar, 2: 'baz'};

Output:

var _0x2c539f = {};
var s = _0x2c539f;
s['1'] = bar

Thank you for the issue, will fix it in a few days, maybe today.

Line with the error:
https://github.com/javascript-obfuscator/javascript-obfuscator/blob/master/src/node-transformers/converting-transformers/properties-extractors/AbstractPropertiesExtractor.ts#L62

Will fixed in #502

Merged. I will release a new version this week.

Error appearing again with your example code:

var s = {0: 'foo', '1': bar, 2: 'baz'};

const options = {
    log: true,
    transformObjectKeys: true

Will check later today

Lol, looks like when i released 0.23.0 version, I forgot to pull origin/master branch.
Will release 0.23.1 in a few hours.

Released, try now please

Yes, now it works

sorry for bothering, but i'm facing the same issues at the 0.27.4 , how can i solve this? by the way, i'm facing this issue when transformObjectKeys is true or false, i think my problem doesn't depend on that variable

Without code, i can't help

@ahmetburakatli

@ahmetburakatli also, here is no 0.27.4 version. Latest version is 0.27.2
