React-native 0.61.2 with hermes disassembling index.android.bundle

$

I created a release build of my app with react-native 0.61.2 and enabled Hermes. In my Crashlytics I receive information about crashes along with stacktraces. Perviously I used to apply apktool to extract index.android.bundle from my apk, and it contained js code where I was able to find the issue by stacktrace.

But now using Hermes index.android.bundle seems to contain bytecode rather than js and I wasted a day trying to disassemble it. The last thing I tried was hbcdump tool mentioned in https://github.com/facebook/hermes/blob/master/doc/BuildingAndRunning.md, but all I get is "Error: fail to deserializing bytecode: Wrong bytecode version. Expected 73 but got 62"

What should I do to disassemble index.android.bundle created with Hermes? Any help is highly appreciated!
