Originally created by @dileep-veya on GitHub (Jul 21, 2025).

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

The Problem is langraph-sdk not including bearer token for assets fetching hence getting 401 error. custom authentication for api is working fine.

SDK Client creation

import { Client } from '@langchain/langgraph-sdk';
import { env } from '~/env';

export function createClient({ auth_token }: { auth_token: string }) {
  const client = new Client({
    apiUrl: env.NEXT_PUBLIC_LANGGRAPH_API_URL,
    defaultHeaders: { Authorization: `Bearer ${auth_token}` },
  });
  return client;
}

useStream initialisation

  const streamValue = useTypedStream({
    apiUrl,
    defaultHeaders: {
      "authorization": jwtToken
    },
    assistantId,
    threadId: threadId ?? null,
    onFinish(state) {
      if (state.values.promptSuggestions) {
        setPromptSuggestions(state.values.promptSuggestions);
      }
    },
    onCustomEvent: (event, options) => {
      if (isUIMessage(event) || isRemoveUIMessage(event)) {
        options.mutate((prev) => {
          const ui = uiMessageReducer(prev.ui ?? [], event);
          return { ...prev, ui };
        });
      }
    },
    onThreadId: (id) => {
      setThreadId(id);
      // Refetch threads list when thread ID changes.
      // Wait for some seconds before fetching so we're able to get the new thread that was created.
      sleep().then(() => refetch());
    },
  });
