UI Bug: Arrow heads missing from non-default node names #107

Open alvinuday opened 2 months ago

I just came across this UI Glitch in Langgraph Studio. When you run the Langgraph Example all arrow heads are visible, but a single change makes the arrow heads disappear. Someone please take a look into it. I have attached the screenshots for your reference. I believe it has something to do with Node colors or something.

Langgraph Studio Version 0.0.20

PS: the code for both agent and Human Interface Agent is the same, including the conditional edges and internal logic, only node name is different, which causes a new color to render in the studio. After which the arrow heads disappear, hence the UI Bug. image image

Another Example: Node Name - human agent, same internal code and logic image
