✔ unknown import canonical_abi has not been defined · general

I have Rust code which I am compiling to wasm, and running that wasm file from wasmtime, wasmtime_wasi and wit_bindgen_wasmtime::import.

I built the wasm file just fine with cargo build --target wasm32-wasi --release, though when trying to run my wasm in a Rust host, I get the following error:

Error: unknown import: `canonical_abi::resource_new_aggregate` has not been defined

variant error {
  command(list<u8>),
  deserialize-event,
  deserialize-command,
}

resource aggregate {
  static new: function(id: string) -> aggregate
  apply-events: function(events: list<list<u8>>) -> expected<unit, error>
  handle-command: function(command: list<u8>) -> expected<list<list<u8>>, error>
}

And I am attempting to call the functions with wit_bindgen_wasmtime::import!("./domain.wit"); and:

let (domain, _instance) =
    Domain::instantiate(&mut store, &module, &mut linker, move |ctx| &mut ctx.domain)?;

let state = domain.aggregate_new(&mut store, "john-doe")?;

let events = domain.aggregate_handle_command(
    &mut store,
    &state,
    br#"{"command":"open_account","params":{"initial_balance":10.0}}"#,
)??;

domain.aggregate_apply_events(
    &mut store,
    &state,
    &events
        .iter()
        .map(|event| event.as_ref())
        .collect::<Vec<_>>(),
)??;

Strangely I had this working some months ago, but when coming back to it, it doesn't seem to work. I've also had to rename domain.new_instance to domain.aggregate_new, domain.handle_command to domain.aggregate_handle_command and domain.apply_events to domain.aggregate_apply_events.

I had posted a code snippet for my future self here: https://github.com/thalo-rs/esdl/tree/main/examples/bank-account-wasm
But like I said, I've had to rename those new_instance, handle_command and apply_events from the code snippet.
I tried using wit from a locked commit d5c8b3960d1bc3a7b7f312991e5923b7fa2a3495, though that didn't change anything.

I think the renaming part I mentioned should be disregarded. That's just because I switched to use a wit resource.
Though the initial error of canonical_abi::resource_new_aggregate has not been defined is still an issue
