@theomonnom any idea why the eventemitter test might be failing? This PR doesn't include any changes around eventemitter 🤔

Was the logic wrong before?

[lukasIO]

it showed up as a type error where lists and dicts were mixed

[lukasIO]

but this might also be as a result of how the map type in proto get's interpreted in proto2 vs proto3 syntax, not sure

That's so weird, it is passing on main, will take a look

@lukasIO @theomonnom I see a similar issue here as in Node - a runtime error about missing required fields when running the basic_room example:

When implementing the proto2 syntax I made all fields required that weren't explicitly marked as optional before. Maybe this also overdid things for the RoomOptions? Not sure if these missing fields should really be required for the FFI request, wdyt @theomonnom ?
