How do I start building on netfly with EJS file? It freezes and won't go on

Hello everyone,
I have a problem publishing a site that I was doing for a company, it’s still in testing so any front end page has to be redone from scratch, it was to test functions, my problem is that I have files with the extension .ejs, and netfly from problems about it, when I deploy it stays in building and doesn’t stop anymore, so it doesn’t create the site.
how could i solve?
here is my repository if anyone wants to take a look. The data I save is saved to mongoDB.

P.S : sorry for my bad english

Should answer is your project won’t work on Netlify. See this guide for more details
