createEventBuilder input parameter bus has type never

[gramliu]

I'm following the guide for setting up an EventBus, but I'm encountering some typing issues with the createEventBuilder function.

import { createEventBuilder, ZodValidator } from "sst/node/event-bus";

export const event = createEventBuilder({
  bus: "bus",
  validator: ZodValidator
});

In the guide, you specify the required parameter, bus. However, I'm getting an error saying its type is never.

I looked at the source and it seems like its type is indeed being assigned to the keys of an empty interface. Is this intentional behavior? I'm also getting the same error with a fresh template created from pnpm create sst test-app

Might've replied to this on Discord. But would appreciate a PR!

Temp workaround:

export const event = createEventBuilder({
  bus: 'bus' as never,
  validator: ZodValidator,
});

Also getting error from default setup pnpm create sst(latest commit fixes)

@jayair To double check, I presume 'bus' must match the 2nd arg of new EventBus(...)?

Given the runtime nature of EventBus, are we happy to type as Bus extends string instead of Bus extends keyof typeof EventBus? Happy to create PR (likely on weekend)

Nvm, running sst build fixes
