koa-ts example doesn't work

[JT Smith]

I'm on an M2 Mac running the latest OS. The regular koa example works, but the typescript one throws a bunch of errors.

jtsmith@jts-MacBook-Pro koa-ts % npm start

> objection-example-koa-ts@3.0.0 start
> npm run migrate && rm -rf dist && tsc && node dist/app.js


> objection-example-koa-ts@3.0.0 migrate
> knex migrate:latest

Since I'm installing this just to learn about objection I'm afraid I can't offer any insights as to why it doesn't work. But the regular koa example worked by just following the instructions.

[Kirk Peterson]

.insertGraph(ctx.request.body as Person)

or

.insertGraph(ctx.request.body as Movie)

as appropriate will fix those
