Can you upload minimal working project where i can reproduce this error? It should be prepared project, i should just install dependencies and build it.

@sanex3339 I can't upload my source code, and I can't even begin to determine how to track down the source of the error, hence reproduce the issue.
If you could give me any advice at all on how to track down the source of the error I'd be happy to provide a repo to reproduce the issue.

You can replace your source code on any other code on which i can reproduce this error
from webpack-obfuscator.

@sanex3339 I haven't the slightest clue where the error originates, hence cannot reproduce or debug on my own. I have tried to reproduce the issue with a number of best guesses at what the issue could be, without any luck.
Do you have any idea how I can track this down when it's not giving me a source for the errors? If I can find the error, I'd be happy to produce a package to demonstrate. Thanks for any advice.

@sanex3339 so I finally revisited this. I manually obfuscated the output javascript using https://github.com/javascript-obfuscator/javascript-obfuscator and it worked without any issues. Do you have any idea how I can prevent the webpack version from relying on sourcemaps? The underlying tool seems to work fine without.
Thanks for any advice you might be able to give.
