What are you trying to achieve or the steps to reproduce?

Trying to serve a directory based on an absolute path, as shown in the example below. Using the example, visiting / in the browser fails to render the directory listing. Visiting a subpath that is a file does work, such as /app.js. However, subpaths that are directories also fail to render their directory listing.

In the example, removing path.resolve() "fixes" the issue. Please note that, in my real app, I have path set to a function and the actual value is determined by some business logic that walks the filesystem and returns an absolute path.

'use strict';

const path = require('path');
const hapi = require('@hapi/hapi');
const inert = require('@hapi/inert');

const server = hapi.server({
    debug : {
        log     : ['error'],
        request : ['error']
    },
    port : 3000
});

const start = async () => {
    await server.register([inert]);

    server.route({
        method : 'GET',
        path   : '/{filepath*}',
        handler : {
            directory : {
                path    : path.resolve('build'),
                listing : true
            }
        }
    });

    await server.start();
};

start();

What was the result you got?

A 500 Internal Server Error, which seems to be caused by inert joining an absolute path with another absolute path, resulting in a path that does not exist. For some reason, this doesn't happen on subpaths that are files.

What result did you expect?

The directory listing should be shown.
