Failed to initialize: list index out of range

First, thanks for making the plugin! This would be a great addition to binja.

Attempting to load a wasm file results in the stack trace below:

BinaryView of type 'WASM' failed to initialize!

I can't seem to upload the file itself to the Github issue, but if you give me an email I can send it your way.

Thank you for the report @CoffeeFlux ! I will be happy to take a look.

Did you try to attach the binary or text for of WASM? if binary, then maybe try converting it to text form with a .txt extension?

[CoffeeFlux]

Unfortunately, it's around 40MB in text form. It also seems that disassembling and reassembling actually results in the file not producing the same error, though it still seems to run into issues.

This link should hopefully work, though I'm not sure how long it will stay alive: https://pomf.lain.la/f/3krt3xg2.wasm
