WasmEdge: exec container process `/add.wasm`: Exec format error error while running runtime: exit status 1

Description

I want to create and run the container image for test. I referred to this article(https://wasmedge.org/book/en/kubernetes/demo/wasi.html). I have followed the mentioned steps to build and install buildah. At the same time, I builded image using the tool buildah.

$ sudo buildah images
REPOSITORY                    TAG      IMAGE ID       CREATED       SIZE
localhost/wasm-wasi-example   latest   d230f65c92e0   4 hours ago   2.01 MB

After, i creates a new working container using the command sudo buidah from localhost/wasm-wasi-example:latest

sudo buildah containers
CONTAINER ID  BUILDER  IMAGE ID     IMAGE NAME                       CONTAINER NAME
67ac345ac1a7     *     d230f65c92e0 localhost/wasm-wasi-example:l... wasm-wasi-example-working-container

Everything is normal up to here, as expected.

However, i want to run a command inside of the container, the following error occurs, exec container process `/add.wasm`: Exec format error error while running runtime: exit status 1. One more question, If I want tocrun to manage a container, how will i do? I find that it is wrong to use crun to run a container that is created by buildah.

Current State

I cannot manage a container using crun or buildah

Expected

Input: sudo buildah run wasm-wasi-example-working-container /add.wasm 2 2 Output: 4
