  • This is a bug, not a usage question. For questions, please use GitHub Discussions.
  • I added a clear and detailed title that summarizes the issue.
  • I read what a minimal reproducible example is (https://stackoverflow.com/help/minimal-reproducible-example).
  • I included a self-contained, minimal example that demonstrates the issue INCLUDING all the relevant imports. The code run AS IS to reproduce the issue.

Example Code

My env setup:

conda create -n langgraph-test -y python=3.12 pip
conda activate langgraph-test

Project setup and starting langgraph studio:

pip install langgraph-cli[inmem]
langgraph new --template new-langgraph-project-python .
pip install -e .
langgraph dev

Then I perform following steps:

  • Click submit (works as expected)
  • Make some small change in code, like add new line
  • Click re-run from here on some node (does not work)

What happens: Re-run seems to start at first, but stops after a second without any errors. All results from nodes bellow clicked one are removed.

Error Message and Stack Trace (if applicable)

No errors

Description

I'm experiencing an issue with the re-run from here feature on locally developed graphs. When I run langgraph dev and use re-run from here without making any code modifications, everything works as expected. However, if I make even a small change to the code, the re-run from here feature stops working for any checkpoints created before the reload.

In other words, I would like to use re-run from here as shown here on video: run graph -> make modification in code -> re-run from here. unfortunately it doesn't work for me.

I'm experiencing this as well, exactly as described. After a code change, clicking "re-run from here" causes a silent failure, and the 'run' completes without any kind of status indication.

same issue.

When I click re-run, the graph starts from the beginning, no matter even if I change the code or not.
Since the graph starts from the beginning, it requires the input again.

Same issue here. Since Langraph Studio Desktop has been deprecated and no cross-platform alternatives are currently available—particularly for Linux and Windows—this significantly impacts our development workflow. It would be great to hear if there's any roadmap or recommendation for a replacement.

Should be fixed now if you update the version of langgraph-checkpoint to >= 2.0.25
