Doesn't work. Template error

[sdwru]

The error is on the lines {{ inertiaHead(page) }} and {{inertia(page) }} in templates/app.html.twig. I see those same functions in the inertia-bundle project which appears to be what this project is based on. Looking at that project, I see those functions defined in Twig/IntertiaExtension.php but I don't see them defined anywhere in this project.

Here is the full stack trace.

Twig\Error\RuntimeError:
An exception has been thrown during the rendering of a template ("Could not resolve host "node".").
