Seems much more discoverable here, no?

If I call one of these unsupported methods locally, how do I know it's not supposed to work, without reading the docs?

[irvinebroque]

If they're not in local dev, and Workflows doesn't work in remote dev, that means...you just have to write code ship to prod and trust it will work? Or am I missing something?

@irvinebroque No, you're correct. pause and resume are not supported locally. However, writing and running a WorkflowEntrypoint is. wrangler dev on a project that exports a WorkflowEntrypoint works and that's what I would classify as local development to assert if something works before shipping to production.

Pause and resume are unsupported at the moment due to a miniflare limitation (killing the engine DO kills all threads unless I'm mistaken). Pause and resume are also often not in the happy path for p90 Workflows use cases so we are happy with that being a foot note for now until we are unblocked.

Guessing link is incorrect. Using them locally throws an Error documenting that they are unsupported at the moment.
