Custom Hook Tokens Cannot Be Reused After Workflow Completion

[rRakarare]

Environment

• Next.js: 15.5.6
• Workflow Devkit: 4.0.1-beta.12

Issue

Workflows with custom hook tokens cannot be rerun. After first completion, attempting to rerun with the same token fails with:

Workflow "wrun_01K9SDEB1B6A1JZHH..." has status "completed", skipping

Reproduction

"use workflow";

// First run - works
const hook = createHook({
  token: `slack_messages:${channelId}`
});
const result = await hook;

// Resume
await resumeHook(`slack_messages:${channelId}`, slackEvent);

// Second run with same channelId - fails with "completed" status

Expected

Should be able to rerun workflows with the same custom token multiple times, with each creating a new workflow instance.

Question

Is this intended behavior? The docs example uses stable identifiers (like channel IDs) which suggests tokens should be reusable. How should recurring workflows with deterministic tokens be handled?

Seems reasonable to me that the token would be freed up after a workflow completes. Can you explain where you're seeing this behavior? i.e. during local dev, deployed to Vercel, etc.

I was only trying in local dev

Ok thanks. So I consider that a bug in the local implementation then. I've started a PR here to fix.
