704 Starting with release 3.3 of the Python plugin, the plugin generates a
705 Python exception derived from class ``orthanc.OrthancException`` if an
706 error is encountered. This exception contains a tuple that provides
707 the error code and its textual description.

710 <https://docs.python.org/3/library/exceptions.html>`__ ``ValueError``.
