The --app-path argument was not working, following changes on ebnode.py to make it work:
def run_npm_install(self, app_path):
        bin_path = self.get_node_bin_path()
        #self.npm_install(bin_path, self.config_manager.get_container_config('app_staging_dir'))
        self.npm_install(bin_path, app_path);
Change user to nodejs

sudo su - nodejs -s /bin/bash
