LangGraph Studio does not work anymore

[colindaniels]

Worked previously, but after a LangGraph studio update was pushed, my unchanged typescript project will error out.

Troubleshooting steps already taken:

• Freshly cloned "react-agent-js" starter template from langgraphjs repo.
• Deleting all docker builds, volumes, images, and containers.
• Reinstalled langgraph studio
• Tried running without langgraph studio (compiling ts and running node), and it runs perfectly.

The project runs as it should, until I try using langgraph studio.

I get the following error: langgraph-api-1 | Process SpawnProcess-1: langgraph-api-1 | Traceback (most recent call last): langgraph-api-1 | File "/usr/local/lib/python3.12/multiprocessing/process.py", line 314, in _bootstrap langgraph-api-1 | self.run() langgraph-api-1 | File "/usr/local/lib/python3.12/multiprocessing/process.py", line 108, in run langgraph-api-1 | self._target(*self._args, **self._kwargs) langgraph-api-1 | File "/usr/local/lib/python3.12/site-packages/uvicorn/_subprocess.py", line 80, in subprocess_started langgraph-api-1 | target(sockets=sockets) langgraph-api-1 | File "/usr/local/lib/python3.12/site-packages/uvicorn/server.py", line 65, in run langgraph-api-1 | return asyncio.run(self.serve(sockets=sockets)) langgraph-api-1 | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ langgraph-api-1 | File "/usr/local/lib/python3.12/asyncio/runners.py", line 194, in run langgraph-api-1 | return runner.run(main) langgraph-api-1 | ^^^^^^^^^^^^^^^^ langgraph-api-1 | File "/usr/local/lib/python3.12/asyncio/runners.py", line 118, in run langgraph-api-1 | return self._loop.run_until_complete(task) langgraph-api-1 | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ langgraph-api-1 | File "uvloop/loop.pyx", line 1517, in uvloop.loop.Loop.run_until_complete langgraph-api-1 | File "/usr/local/lib/python3.12/site-packages/uvicorn/server.py", line 69, in serve langgraph-api-1 | await self._serve(sockets) langgraph-api-1 | File "/usr/local/lib/python3.12/site-packages/uvicorn/server.py", line 76, in _serve langgraph-api-1 | config.load() langgraph-api-1 | File "/usr/local/lib/python3.12/site-packages/uvicorn/config.py", line 434, in load langgraph-api-1 | self.loaded_app = import_from_string(self.app) langgraph-api-1 | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ langgraph-api-1 | File "/usr/local/lib/python3.12/site-packages/uvicorn/importer.py", line 19, in import_from_string langgraph-api-1 | module = importlib.import_module(module_str) langgraph-api-1 | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ langgraph-api-1 | File "/usr/local/lib/python3.12/importlib/init.py", line 90, in import_module langgraph-api-1 | return _bootstrap._gcd_import(name[level:], package, level) langgraph-api-1 | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ langgraph-api-1 | File "", line 1387, in _gcd_import langgraph-api-1 | File "", line 1360, in _find_and_load langgraph-api-1 | File "", line 1331, in _find_and_load_unlocked langgraph-api-1 | File "", line 935, in _load_unlocked langgraph-api-1 | File "", line 995, in exec_module langgraph-api-1 | File "", line 488, in _call_with_frames_removed langgraph-api-1 | File "/api/langgraph_api/server.py", line 14, in langgraph-api-1 | File "/api/langgraph_api/lifespan.py", line 9, in langgraph-api-1 | File "/api/langgraph_api/queue.py", line 15, in langgraph-api-1 | File "/api/langgraph_api/shared/stream.py", line 21, in langgraph-api-1 | File "/usr/local/lib/python3.12/site-packages/langgraph_storage/store.py", line 6, in langgraph-api-1 | from langgraph.store.base import BaseStore, V langgraph-api-1 | ImportError: cannot import name 'V' from 'langgraph.store.base' (/usr/local/lib/python3.12/site-packages/langgraph/store/base/init.py)

Yes! This is also my experience. No changes to my project, and randomly this evening things stopped working. I want to add that I'm not using Typescript, and this error still occurs.

I also tried resetting my entire docker environment, deleting LangGraph Studio application and all preferences/caches, reinstalling, and running the sample project—same error.

I tried changing the python version and specifying the langgraph version of requirements.txt, but the same error is occurring. Maybe it's a problem with the distributed docker. It worked well until yesterday, but it's not working now.

[dastan92]

Getting the same error. Reinstalled dependencies. I am using python and getting the same error. Was working until 3 hours before.

[colindaniels]

Yeah, just switched over to python, still getting the same errors. This problem isn't exclusive to typescript. I'll change the title.

Oh it works well I fix the langgraph version to requirements.txt and it works fine. I used langgraph==0.2.28 Thanks @rvndbalaji.

Hello, we apologise for the inconvenience caused by a versioning bug. We've cut a new image which should address the issue. The API image should be pulled automatically by restarting the project or reopening Studio

Hello @liezl200! This seems to be an upstream issue with tiktoken, which should be resolved. Do let us know if the issue still persists.
