hapi-openapi prevents application using @hapi/glue v7.0.0 and @hapi/hapi v19.1.1 on starting due to no validator being configured

[edward-whittle]

The latest version of Hapi requires a Validator to be configured as per this issue for this release.

The issue can be replicated by removing the hapi-openapi plugin which allows the server to start

plugin-hapi-openapi

exports.plugin = {
  plugin: require('hapi-openapi'),
  options: {
    api: require('path').resolve('./config/swagger.yaml'),
    handlers: require('path').resolve('./handlers'),
    docs: {
      path: 'api-docs',
    },
  },
};

Manifest for Glue.compose

/* eslint-disable max-len */
const returnXVHeader = require('../plugins/plugin-xv-header').plugin;
const hapiOpenAPI = require('../plugins/plugin-hapi-openapi').plugin;
const hapiAlive = require('../plugins/plugin-hapi-alive').plugin;
const hapiPino = require('../plugins/plugin-hapi-pino').plugin;
const validateAcceptHeader = require('../plugins/plugin-preresponse-error').plugin;
const validateContentType = require('../plugins/plugin-validate-content-type').plugin;

const plugins = [
  returnXVHeader,
  // hapiOpenAPI, Commenting out allows server to start
  hapiAlive,
  hapiPino,
  validateContentType,
  validateAcceptHeader,
  {
    plugin: require('@hapi/vision'),
  },
  {
    plugin: require('@hapi/inert'),
  },
  {
    plugin: require('hapi-swagger'),
  },
];

exports.manifest = {
  server: {
    host: '0.0.0.0',
    port: 3001,
  }, register: {
    plugins: plugins,
  },
};

[edward-whittle]

This issue can be fixed by adding the following to the register function in lib/index.js

server.validator(require('joi')); //Add this line
const validation = Joi.validate(options, optionsSchema); //Above this line
