What is causing the error "Cannot set uncompiled validation rules without configuring a validator" in NodeJS?

Question

Here's what I have so far.

'use strict';

const Hapi = require("@hapi/hapi");
const Joi = require("@hapi/joi")

const server = new Hapi.Server({ host: "0.0.0.0", port: 80 });

server.route({
    method: "POST",
    path: "/board",
    options: {
        validate: {
            payload: {
                name: Joi.object({
                    name: Joi.string().min(1).max(15)
                })
            }
        }
    },
    handler: async (request, h) => {
        // do stuff
    }
});

server.start();

This produces the error

I expected this to validate the request, but instead it's producing an error message that there are very few details on how to fix.

It should be

'use strict';

const Hapi = require("@hapi/hapi");
const Joi = require("@hapi/joi")

const server = new Hapi.Server({ host: "0.0.0.0", port: 80 });

server.route({
    method: "POST",
    path: "/board",
    options: {
        validate: {
            payload: Joi.object({
                    name: Joi.string().min(1).max(15)
                })
        }
    },
    handler: async (request, h) => {
        // do stuff
    }
});

server.start();

payload: Joi.object({ name: Joi.string().min(1).max(15) })
