Describe the Bug

Observed behavior

Error: Handler does not export a fetch() function. When using SELF with vitest and WorkerEntrypoint

Expected behavior

Vitest should work with WorkerEntrypoint not just export default fetch.

Steps to reproduce

Does not work:

export default class extends WorkerEntrypoint<Env> {
  async fetch(request: Request) { return app.fetch(request, this.env, this.ctx)}
}

Works:

export default {
  async fetch(request: Request): Promise<Response> { return app.fetch(request) }
}
