Can't read docker manifest when cpio archive build with dockerfile is given as an argument to kraft run

[JohnLuke77]

Hi,
I am trying to port the openplc app (https://github.com/thiagoralves/OpenPLC_v3?tab=readme-ov-file) to unikraft,the build step with the file system created with dockerfile (as initrd )works fine but when i try to do kraft run with --rootfs i have the following error:

$ kraft run --log-type basic --log-level debug --rootfs initramfs-x86_64.cpio -M 3000M .unikraft/build/openplc_unikraft_qemu-x86_64
D kraftkit 0.8.7

[?] multiple runnable contexts discovered: how would you like to proceed? run the cwd's Kraftfile and use '.unikraft/build/openplc_unikraft_qemu-x86_64' as arg(s)
i use --as=kraftfile-unikraft to skip this prompt in the future
D using compatible context candidate=kraftfile-unikraft

I already tried with sudo,furthermore using docker login with an access token doesn't work.Has somebody encountered a similar problem?
These are the kraftfile (taken from this example where I deleted the einitrd option: https://github.com/unikraft/catalog/tree/main/library/nginx/1.25 ) and dockerfile used:
files.zip
