Frontend error connecting to langgraph studio.

[turtle3791]

Hi
I have sqllite running and I am able to connect to it using langgraph studio.
I am able to run queries against the sample dataset from langgraph studio.
I took the URL from langgraph studios UI for example: http://localhost:51261
and updated my .env in frontend folder as follows

frontend/.env:
NEXT_PUBLIC_SQLITE_URL=http://localhost:3001
LANGGRAPH_API_URL=http://localhost:51261

However when I try to execute the query from the front I get the following error:
Error in run: TypeError: fetch failed
