Hapi unknown authentication strategy jwt - node.js

Question

I'm getting the error Hapi unknown authentication strategy jwt but I'm not sure why. I'm certain I've probably set something up wrong but here's my server index.js:
Should i be using a different auth strategy? Also stackoverflow won't let me submit my question because it's mostly code but I'm not sure what else to submit. All of the details are here and I don't know what else to add to provide any more information that i can. I'm just using using auth with config.auth.strategy and jwt in an array.
const Hapi = require('#hapi/hapi');
const objection = require('objection');
const knex = require('./knex');
const authService = require('./auth/auth-service');
const JWTAuth = require('hapi-auth-jwt2');
const init = async () => {
const server = Hapi.server({
port: 9000,
host: 'localhost',
routes: { cors: {
origin: ['*'],
headers: ['Authorization'],
exposedHeaders: ['Accept'],
additionalExposedHeaders: ['Accept'],
maxAge: 60,
credentials: true
}}
});
objection.Model.knex(require('./knex'));
await server.register([
{plugin: JWTAuth},
{
plugin: require('./movies/movie-routes'),
routes: {prefix: '/movies'}
}, {
plugin: require('./user/user-routes'),
}
])
server.auth.strategy('jwt', 'jwt',{
key: authService.jwtKey,
validate: authService.validateJWT,
verifyOptions: {algorithms: ['HS256']},
errorFunc: (err)=> {return err},
cookieKey: 'id_token'
})
await server.start();
console.log('Server running on %s', server.info.uri);
};
process.on('unhandledRejection', (err) => {
console.log(err);
process.exit(1);
});
init();

Seems like there is a problem with authService.validateJWT I have added an example of HapiJs jwt authentication please it once for your reference
const Hapi = require('#hapi/hapi');
const JWTAuth = require('hapi-auth-jwt2');
const init = async () => {
const server = Hapi.server({
port: 9000,
host: 'localhost',
routes: {
cors: {
origin: ['*'],
headers: ['Authorization'],
exposedHeaders: ['Accept'],
additionalExposedHeaders: ['Accept'],
maxAge: 60,
credentials: true
}
}
});
await server.register([
{ plugin: JWTAuth }
])
server.auth.strategy('jwt', 'jwt', {
key: 'your-key',
validate: async function (decoded, request) {
if (!decoded) {
return { isValid: false };
} else {
request.auth.credentials = {
'user': decoded,
'token': request.headers['authorization']
};
return { isValid: true };
}
},
verifyOptions: { algorithms: ['HS256'] },
cookieKey: 'id_token'
});
server.auth.default('jwt');
server.route({
method: 'GET',
path: '/',
handler: (request, h) => {
return 'Hello World!';
}
});
await server.start();
console.log('Server running on %s', server.info.uri);
};
process.on('unhandledRejection', (err) => {
console.log(err);
process.exit(1);
});
init();
