Hi,

maintainer of yfiles-jupyter-graphs here. We have just recently been made aware of an issue in JupyterLab 4.3 (see Failed to create view for 'GraphView' · Issue #64 · yWorks/yfiles-jupyter-graphs · GitHub) that we have fixed immediately.

The error message was similar to the one you are reporting here. Therefore, please try to update yfiles-jupyter-graphs to v1.10.1 and see whether this fixes it on your end as well.

If this does not help, can you send an extended exception stack or how to create a failing environment?

Fabian
