Error: Cannot add duplicate edge [Edge-Id] -> [Edge-Id] about javascript-deobfuscator HOT 6 CLOSED

Yes that script is obfuscated with a custom obfuscator so you'll need to make a custom deobfuscator for it (this repo is for general deobfuscation, not targeted towards any specific obfuscator). It shouldn't be too hard, looks like some standard string encoding and a confused attempt at control flow flattening.

Thanks, the error is gone but it's not deobfuscated, unfortunately. :/
