dicej opened issue #12187:

Currently, wasmtime run's invoke_component function uses Func::call_async to invoke the function. However, that will only run the guest task until it produces a result, then print that result an exit. Ideally, it would use Func::call_concurrent instead, which returns a TaskExit which can be used to await the completion of the task, allowing any post-return operations to finish.

Hey just to check, this was closed by https://github.com/bytecodealliance/wasmtime/pull/12185, right?

That handled executing the wasi:cli/run function, but this is the follow-up for --invoke which manually selects a function and invokes it. Effectively this needs to use call_concurrent and then use the second TaskExit return value
