buildah: unknown shorthand flag: 'i' in -i

If I am to launch a container with podman I can use the -ti flags to connect my terminal to the container, $ podman run -ti centos:7 /bin/sh sh-4.2# exit But the same option I build with buildah it returns $ buildah run -ti $(buildah from centos:7) /bin/sh unknown shorthand flag: 'i' in -i What is the right method to invoke buildah?
