Unable to build production version on Ubuntu

Hi - the product looks interesting, would like to try it out, but can't build it. Here is my terminal history (fresh install):

   16  sudo apt-get install -y git cmake curl python3 build-essential pkg-config libsecret-1-0 libsecret-1-dev ca-certificates openssh-client dpkg-dev dpkg-sig
   17  curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.2/install.sh | bash
   18  exit
   19  nvm install 14.19.0
   20  cd git
   21  git clone git@github.com:cattr-app/desktop-application.git
   22  ssh-keygen
   23  cd ~/.ssh
   24  ls
   25  cat id_rsa.pub 
   26  cd ~/git
   27  git clone git@github.com:cattr-app/desktop-application.git
   28  ls
   29  cd desktop-application/
   30  nvm use 14.19.0
   31  npm i -g yarn
   32  yarn -v
   33  yarn
   34  yarn package-linux
   35  npm config set git-tag-version false
   36  yarn package-linux
   37  npm version v1.0.0
   38  yarn package-linux
   39  ls
   40  ls target
   41  cd target
   42  ls
   43  ./Cattr.AppImage --register
   44  ./Cattr.AppImage 
   45  history

And here is the error:

This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason:
