Using Vite (V5) requires plugin opts.

[TylerAtCodeOfLife]

import { defineConfig } from 'vite'
import pattycake from 'pattycake'

// typescript wants pattycake.vite(options)
export default defineConfig({
plugins:[ pattycake.vite() ]
})
// the options type HirCodegenOpts just has a bool for chaining so i fixed it as such
export default defineConfig({
plugins:[ pattycake.vite({disableOptionalChaining: true}) ]
})
