Error: Os { code: 2, kind: NotFound, message: "No such file or directory"

I successfully built the hello_c instance in Occlum following the instructions in the README.md, the Occlum instance is located in the demos/hello_c/occlum_instance directory, which could normally execute with the command occlum run /bin/hello_world:

However, when I try to build a new hello_c instance in Occlum following the instructions today, some error occurs.
The commands are as below:

occlum new occlum_instance2
cd occlum_instance2
rm -r ./image/
copy_bom -f ../hello.yaml --root image --include-dir /opt/occlum/etc/template
occlum build --sgx-mode SIM
occlum run /bin/hello_world

Then I got the error:

Is there any bug in the built-in occlum in the docker?
My docker version is latest-dev-f4db1c9-ubuntu20.04.
