Bug in v4 upgrade docs?

[djacobs7]

Are we certain that this works?

I was reading this doc for my upgrade: https://trigger.dev/docs/migrating-from-v3

I tried this, but I got a runtime error, and also a typescript error.
const runs = await batchHandle.runs.list();

I had to do this instead
const r = await batch.retrieve(handle.batchId);
