Jupyter - 500 : character maps to <undefined>

I am a new Python user. I just installed Jupyter notebook, and typed “jupyter notebook” in Anoconda Powershell. After clicked New dropdown and selected Python 3, i got a message "500 : character maps to ". Can anyone tell me how to fix this issue?

Hi @gjiang4 and welcome to the community!

I don’t have any experience with this error myself but it seems like “Error 500” is a catch all error code and could be caused by many things. The most popular suggestion for fixing these errors is to update jupyter. Try running:

conda update jupyter

Also, have you tried a good ol’ fashioned reboot? :sunglasses:

Yes, this fixed my issue. Thank you so much mathmike314!!
