Unable to build for webos in version2.7.3

[Joao Pedro Silva Faria]

I have downloaded from the git and followed the steps in the readme.
I still have a problem when running the server that I have to add "zombiebox-platform-pc": "^2.3.3" to package .json on the dependencies.
after this I can run a localhost web server.
I am unable to build a version to deploy on WebOS, this is the output in the console, could you please help ?
