vagrant up fails in my setup

[crs1138]

I get following error message –

failed:` [default] (item=roots-example-project.com) => {"changed": false, "item": {"key": "roots-example-project.com", "value": {"admin_email": "admin@roots-example-project.test", "cache": {"enabled": false}, "local_path": "../site", "multisite": {"enabled": false}, "site_hosts": [{"canonical": "roots-example-project.test", "redirects": ["www.roots-example-project.test"]}], "ssl": {"enabled": false, "provider": "self-signed"}}}, "msg": "Composer could not find a composer.json file in /srv/www/roots-example-project.com/current To initialize a project, please create a composer.json file as described in the https://getcomposer.org/ \"Getting Started\" section", "stdout": "Composer could not find a composer.json file in /srv/www/roots-example-project.com/current\nTo initialize a project, please create a composer.json file as described in the https://getcomposer.org/ \"Getting Started\" section\n", "stdout_lines": ["Composer could not find a composer.json file in /srv/www/roots-example-project.com/current", "To initialize a project, please create a composer.json file as described in the https://getcomposer.org/ \"Getting Started\" section"]}

Why oh why is the entry level so difficult on trellis/bedrock? :(
