Custom Error Messages

Hi All,

I’m working on an extension that modifies the error messages to be more custom. I haven’t been able to get anywhere with it, does anyone have any idea if this is possible? If so how?

Do you want to change existing error messages in JupyterLab? Or do you want to create/show new error messages when certain event happens?

In any case, searching for showErrorMessage method in JupyterLab would be a good starting point. Also checkout showDialog method if you want more customization.
