Need help with using disko

I’m using nixos-anywhere to install a system, this is my settings of disko.
According the manual, I ran nix run github:numtide/nixos-anywhere -- --flake flake.nix#nixos --vm-test to test my config. Unfortunately, It could not run correctly, and throw some errors.
What should I do for this?

I’m not sure, but could it be vda instead of sda ?

It has not been fixed, and the log shows that it is not important.
