Is it safe to use config.__pregel_task_id as the node id?

[wenshen35105]

Hi, I am looking for a node ID which will be the same even if the node is interrupted. I noticed the langgraph runtime passes a __pregel_task_id within the config.configurable object and the id is the same even if the node is resumed from interruption. However, the variable is not exposed from the Langgraph lib. I am wondering if it is safe to use the id. Thanks a lot.

what are you trying to do?

Thanks for the quick reply. I am treating each node as a standalone graph and I am looking to use the __pregel_task_id as the thread_id for those graphs.
