Hi! This notebook has just been updated. Can you try the new version and let us know if you still encounter the error please? Thank you!

[JosephKarpinski]

Downloaded GitHub updated notebooks https://github.com/spacetelescope/jdat_notebooks/tree/main

Same error using jdaviz 3.7.1

pip install upgrade jdaviz 3.8.0

Same error

[camipacifici]

Thank you for trying with the updated notebook and the newest version of jdaviz. Unfortunately, we do not test in VScode and we do not really support it. Is there any chance you could use Jupyter Notebook or Lab outside of VScode?

[JosephKarpinski]

You're right. It works under Jupyter Notebook but not VSCODE. I should have tried that. Please close.

Thank you!

Best Regards,

Joseph Karpinski

Glad it's solved! Feel free to open new issues if you have any other problem.
