Cannot work after bun build

[seepine]

I use simplewebauthn/server in bun

import 'reflect-metadata'
import {
  generateRegistrationOptions,
  verifyRegistrationResponse,
  generateAuthenticationOptions,
  verifyAuthenticationResponse
} from '@simplewebauthn/server'

And build as singlefile

import { build } from 'bun'

const res = await build({
  entrypoints: ['src/index.ts'],
  target: 'bun',
  minify: true,
  sourcemap: 'linked',
  outdir: 'dist',
  compile: { outfile: 'app' },
  define: {
    'process.env.NODE_ENV': JSON.stringify('production'),
  },
})

But got error

elysia-template-1  | 1 | if (typeof Reflect === "undefined" || !Reflect.getMetadata) {
elysia-template-1  | 2 |     throw new Error("tsyringe requires a reflect polyfill. Please add 'import \"reflect-metadata\"' to the top of your entry point.");

Interesting. If you run bun list --all do you see the reflect-metadata package as a dependency of @peculiar/x509, which is a dependency of @simplewebauthn/server@13.2.0 and up?

$ bun list --all

Huh, tsyringe and reflect-metadata seem to be present...I have to admit I'm not a Bun expert so I'm not sure what's going on here. Is @simplewebauthn/server otherwise working as expected in your Bun project?
