Dap-php-setup not working

[Father2303]

I am running Nixos unstable with doom emacs 28.1 nativeComp. In Nixos i have the following packages installed for emacs:

    ((emacsPackagesFor emacs28NativeComp).emacsWithPackages
      (epkgs: [ epkgs.vterm ]))
    fira-code
    fira-code-symbols
    git
    gnumake
    gnupg
    graphviz
    html-tidy
    jq
    # kotlin
    # kotlin-language-server
    # ktlint
    nixfmt
    nodejs
    nodePackages.bash-language-server
    # nodePackages.intelephense
    nodePackages.js-beautify
    nodePackages.npm
    nodePackages.prettier
    nodePackages.stylelint
    nodePackages.typescript-language-server
    nodePackages.vscode-langservers-extracted
    pandoc
    scrot
    shellcheck
    shfmt
    wordnet

I have php configured as follows:

    php
    php.packages.php-cs-fixer
    # php.packages.psalm
    # php.packages.phpstan
    php.packages.composer
    (pkgs.php.buildEnv {
      extensions = ({ enabled, all }: enabled ++ (with all; [ xdebug ]));
      extraConfig = ''
        zend_extension=xdebug
        xdebug.mode = debug
        xdebug.start_with_request = yes
        xdebug.discover_client_host = 1
        display_errors = on
        display_startup_errors = true
        html_errors = true
      '';
    })

In init.el i have (debugger +lsp).

Running M-x dap-php-setup in emacs yields wrong type argument: stringp, nil.

Running +debugger/start yields Debug session process exited with status: exited abnormally with code 1.

What do i have to do to make it work?

I found the solution. I had to install unzip. Now at least dap-php-setup works.
