Hello! I'm using the expand and collapse feature and am getting a "multiple roots" error. Does anyone know of an efficient way to identify which node is causing the error? I have about 100 nodes in the flow and it's taking a lot of time to try to find it manually.

I found the problem after much manual labour (double checking every single node and edge ID myself). The cause was a duplicate edge ID.
Do you have any ideas for a general/programmatic approach to discover the cause of the "multiple roots" error?
