toASM throws TypeError: Cannot read properties of null (reading 'map')

[O2rki]

Happens when decompile returns a null object, then toASM tries to map. https://github.com/bitcoinjs/bitcoinjs-lib/blob/6396fb488df79dd7cb27eb1b5f9fb56318055ff5/src/script.js#L158-L162

Do I have to check myself (in my code) if decompile returns a null before calling toASM?.

[jasonandjay]

We can optimize decomplie return value to avoid type error.

But you should check your logic why get incorrect chunks to exec toASM?

[O2rki]

I was debugging the lib. Incorrect chunks may get there for whatever reason.

[jasonandjay]

OK, we will fix it.

Thanks @jasonandjay
