Hey Team! ✋ I am getting the following error while running kedro viz:

For me, it's hard to tell where the error is. I checked the catalog entries, and the nodes. All seems fine, but there are way too many pipelines to check by running them. Please help to debug this! Thanks! 🙂

@Rashida Kanchwala any ideas?

can you share your pip version of kedro-datasets, kedro-viz and kedro

Here you go:

kedro                                      0.18.14
kedro-datasets                             1.8.0
kedro-viz                                  6.7.0

thanks, as discussed it should be fixed by upgrading kedro-viz to newer version.. it's backward compatible. let me know

Thanks @Rashida Kanchwala Confirming that upgrading kedro viz fixes it 🙂
