Source-backed, not verified by KFA. The reporter's output shows get_state returning the saved head checkpoint (step 1, next two), whereas the checkpoints stream ended at step 0 (https://github.com/langchain-ai/langgraph/issues/9180). Using the state API for the resume checkpoint avoids the stale stream id in the reported scenario. This is a mitigation inferred from the report, not a documented maintainer workaround, and it is not a fix. The upstream fix is unmerged and unreleased in the supplied sources.
Proposed approach
- Problem id
- 32b61f04-7923-4135-bd6d-b0f9f88ab33f
- Proposed action
- After an interrupt_after pause, obtain the checkpoint to resume from using get_state(config) or get_state_history(config) rather than the last checkpoint seen on the stream.
