Langgraph studio not showing up

[jonathan1]

I don’t see anymore the Langgraph studio platform (was working up to yesterday).

I tried with a fresh version of the api and sdk and a basic graph

I ran langgraph dev and go the url (LangSmith) as usual, but it only returns a blank screen.

I do see the api docs though.

I tried on firefox and chrome

langchain-core          0.3.74
langgraph               0.6.4
langgraph-api           0.2.129
langgraph-checkpoint    2.1.1
langgraph-cli           0.3.6
langgraph-prebuilt      0.6.4
langgraph-runtime-inmem 0.6.12
langgraph-sdk           0.2.0
langsmith               0.4.13
python 3.12

thanks for any help

@jonathan1 Thanks for flagging, I’m able to reproduce this issue and we’ll put up a fix asap. Do you have a LangSmith account? It appears that this happens if you are not logged in, so would recommend logging in to your account for now if you have one

I do not have a LangSmith account. Is it required or advised to have one ?

It was working w/o an account

Hi both, since yesterday (08/22), I’ve been experiencing this bug again. LangGraph Studio returns a blank screen, regardless of whether I’m logged into my LangSmith account (EU West data region) or not. Any hints or suggestions? TIA!
