Same problem here, any ideas?

It turns out that using

let (command, _instance) = wasmtime_wasi::bindings::sync::Command::instantiate(
        &mut store,
        &component,
        &mut linker,
    ).unwrap();

to instantiate the component make preopened_dir to work, but using

let example_res = Root::instantiate(&mut store, &component, &linker);
    match example_res {
        Ok((instance, _)) => {
            instance.interface0.call_funcall(&mut store).unwrap();
        }
        Err(e) => println!("Error at calling function {:?}", e),
    }

fails.

We use a reactor component, so I think we are missing some wasi initialization step, we just cannot figure out which one.
