How to access data from a past thread inside a node when using langgraph cloud ?

[dyingg]

The langgraph platform deployment and IDE are great for my purposes.

I was thinking of a situation where I would like to fetch the state of a past graph run inside a node, I could store this value in the store as well infact that's what Im going to do to keep list of thread_ids opened by the user, but I think it would be wasteful from a memory utilisation perspective as the data I need is the final state of the past thread run which is already stored.

Since I am not passing my own checkpointer while compiling the graph, Im not sure how I should access this when running the IDE locally and in a production deployment via langgraph platform?

Hello @dyingg!
With @langchain/langgraph-sdk 0.2.64 you should be able to create a new Client() that connects directly to the LG API (without the need to specify apiUrl) and use that to access the past thread state using client.threads.getState(...)
