I am trying to create a systemd service using home-manager using rclone to mount a remote service, but it refuses to allow me to mount. I can mount manually, so it is not clear to me where it goes wrong.

I tried the solutions here, here, and here but without success.

Here is my home-manager config i use:

{ config, pkgs, lib, ... }:
let
  createRcloneMountService = { name, remote, mountPath ? "/home/${config.home.username}/${name}", remotePath ? "/" }: {
    Unit = {
      Description = "Rclone mount service for ${name}";
      After = [ "network-online.target" ];
    };

    Service = {
      ExecStartPre = "${pkgs.coreutils}/bin/mkdir -p ${mountPath}";
      ExecStart = ''
        ${pkgs.rclone}/bin/rclone mount 
          --config /home/${config.home.username}/.config/rclone/rclone.conf 
          --vfs-fast-fingerprint 
          --vfs-cache-mode full 
          ${remote}:${remotePath} ${mountPath}
        '';
      ExecStop = "${pkgs.fuse3}/bin/fusermount -u ${mountPath}";
      Type = "notify";
      Restart = "on-failure";
      RestartSec = "10s";
      Environment = [ "PATH=/run/wrappers/bin/:$PATH" ];
    };

    Install = {
      WantedBy = [ "default.target" ];
    };
  };

in
{

  home.packages = with pkgs; [
    rclone
    fuse3
  ];

  systemd.user.startServices = true;
  systemd.user.services = {
    # Create the rclone mount services by calling the function with the desired parameters using named arguments
    rclone-mount-dropbox-private = createRcloneMountService {
      name = "dropbox-private";
      remote = "dropbox-private";
    };
  };

}

I konw it works on my NixOS config on another machine using the nixos/configuration.nix but when I migrate it to home-manager i get the error:
