partywhen: Some methods incorrectly return 'never' in TypeScript

[jahands]

I tried to use this in a project, but am finding it difficult to get it working due to incorrect return types on some methods:

Any idea how to fix this?

Repro here: https://github.com/jahands/partywhen-typescript-repro/blob/main/src/index.ts

To test, run pnpm install and then hover over the scheduler.scheduleTask() call in index.ts

I tracked this down to Rpc.Result type thinking that Task is not seralizable. Removing the seralizable check here allows Task to show in the return type:

Of course, this is not a solution... I'm just not sure why it thinks Task is not serializable (it passes the value over RPC just fine from my testing).

Ok I think I found the issue within partywhen - unknown is not seralizable. @threepointone can we make this a seralizable type instead of unknown?

If we change the value in the record to Rpc.Seralizable, it fixes it:
