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

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

    at Function.Module.runMain (internal/modules/cjs/loader.js:1025:10)
    at internal/main/run_main_module.js:17:11

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.

On upgrading to Latest hapi, check your code for route validate and response.schema settings and if you are passing values that must be compiled (see above for the lack of Joi.object() as a typical case), either wrap your schema with Joi.object() or call server.validator(Joi)

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) })
