Why are args I pass to newInstance are ignored?!

npx aragon run --prepublish-script "npx truffle migrate" --environment default --template-args \"0xc382601c728b01B084f7Bfff2d901976400Bb07F\" --fn-args 0xc382601c728b01B084f7Bfff2d901976400Bb07F --template-init \"0xc382601c728b01B084f7Bfff2d901976400Bb07F\") does not work: types/values length mismatch (count={"types":1,"values":0}, value={"types":[{"name":"_ownedContract","type":"address"}],"values":[]}) * - what is my error?!

function newInstance(address ownedContract) public
