Usage

Source

exceptions.FastAPIChameleonNotFoundException(
    message=None, four04template_file="errors/404.pt"
)

Raised by not_found() and caught by the template() decorator, which renders template_file with an HTTP 404 status. You normally raise it indirectly via not_found() rather than constructing it yourself.
