Does --instructions-deploy not work?

Tried this:
_npx --yes @flydotio/dockerfile@latest --alpine --add git --add openssh --instructions-deploy=install.packages --force_

output

_file:///Users/xxx/.npm/_npx/f37d7377d96e8c81/node_modules/@flydotio/dockerfile/index.js:307
df.instructions[stage] = options.instructions[stage]
^

TypeError: Cannot create property 'deploy' on string 'install.packages'

Both --instructions-deploy and --instructions have this error, --instructions-build works ok.
