Hi Olle G., I'm the engineer for the agent visualization.
What you're seeing with the missing END is the path actually looping back on itself. If you look verrrry closely, you can see the line from tools going back up to the summarize node with an arrow pointing to the top of that node. Unfortunately the visualization here isn't perfect but it's something we're working on.
Given this loop, it is difficult for us to assume what constitutes the end of the agent flow.
This loop is also the reason that the path view is broken. The sankey diagram that we use does not support circular paths, though we should have a more graceful error message.
One thing we see with langgraph traces is that the instrumentation includes a lot of nodes called "agent" and "tools". Some of our customers requested that we filter these nodes out for them as it results in a lot of noise in the diagram, since these nodes are langgraph artifacts and are not business logic nodes. When I filter out these nodes in the vis, you can see that the graph does have an end node and that the sankey diagram is fixed.
Would you like me to apply this filter for your account?
