shiny.types.SafeException#

class shiny.types.SafeException#

Throw a safe exception.

When shiny.App.SANITIZE_ERRORS is True (which is the case in some production environments like RStudio Connect), exceptions are sanitized to prevent leaking of sensitive information. This class provides a way to generate an error that is OK to be displayed to the user.

Example

#| standalone: true
#| components: [editor, viewer]
#| layout: vertical
#| viewerHeight: 400
