Looks like you're trying to decompile an android React Native bundle - These aren't actually a JS bundle, which explains the reason for getting a syntax error. Android React Native bundles are compiled to Hermes bytecode.

This tool can only handle non-binary JS monolithic React Native Bundles (like the ones produced for iOS builds)

That said;

Since React Native 0.64, Hermes also runs on iOS. To enable Hermes for iOS, edit your ios/Podfile file and make the change illustrated below:

So this tool perhaps may become somewhat obsolete in the future.

https://github.com/P1sec/hermes-dec or https://github.com/bongtrop/hbctool looks like tools which can be used to decompile Hermes bytecode
