Checked other resources

  • I added a very descriptive title to this issue.
  • I searched the LangGraph.js documentation with the integrated search.
  • I used the GitHub search to find a similar question and didn't find it.
  • I am sure that this is a bug in LangGraph.js rather than my code.
  • The bug is not resolved by updating to the latest stable version of LangGraph (or the specific integration package).

Example Code

let runId: string | null = null;
const state = await client.runs.wait(null, "assistant-id", {
  input: {},
  onRunCreated: (params) => {
    // never called in local env
    runId = params.run_id;
  },
});

Error Message and Stack Trace (if applicable)

No response

Description

Just want to report this, it's working in our production LGP, but not in local dev. I didn't even see it in the schema.
