Error on moving nodes with connected links

When I try to select nodes with links connected and move it, the links and nodes are disconnected and throws error.

This error happens after upgrading goJS from 1.8.38 to 2.1.56

What is your code that results in the error?

On error attached above, there is no files from our code in error stack.
It is pointing to files from library.


From the above diagram I am trying to drag selected objects, this results in error on console,
Link remains in original position and only nodes move, making it look disconnected.

What are the first exceptions that you encounter?

For now I’ll assume that this topic is effectively the same as Error on link reshaping
