Description of issue

I wrote a cask as follows and the installation failed

cask "copies" do
  version "3.5.0"
  sha256 "9c7b01e911c4aacd841a1962d8ff677bec48d377759d79c03111c0ff354fd122"

  url "https://clipber.com/getmac"
  name "Copies"
  homepage "https://home.clipber.com/"

  depends_on macos: ">= :high_sierra" 

  app "Copies.app"

  zap trash: [
    "~/Library/Caches/manager.clipboard.kuaitie",
    "~/Library/HTTPStorages/manager.clipboard.kuaitie",
    "~/Library/Preferences/manager.clipboard.kuaitie.plist",
    "~/Library/WebKit/manager.clipboard.kuaitie",
  ]
end

The error message is as follows:

I took a look at the .dmg that it downloads. The app name is actually kuaitie.app, so try that instead of Copies.app.

Thanks for the answer, it's name is indeed kuaitie.app,I installed it successfully!
