I built an intelligent customer service using Langgraph, which contains a number of nodes. My Langgraph runs synchronously and is operating within a Flask application.
It works well under normal circumstances, but sometimes the Graph gets stuck without warning. There’s no response after executing graph. stream, and even though I added log printing at the entry of the graph’s first node, the code doesn’t even reach that point.
Are there any solutions to this problem? Everything else runs fine, and I’ve never encountered this issue before.
The version of my Langgraph is langgraph~=0.4.8.
hi @MrZHui888
could you share your code?
And share your dependency versions as well please.
I assume you are running it on local machine.
