The document could not be created or updated because the
request is missing required information. Form-based requests must
include a nonce, which is a unique key that the server provides and
uses to prevent cross-site form attacks. The nonce was either missing
or invalid.
User response
Contact the administrator and report this message
and the incident ID {0}. The administrator must ensure that the client
application supports nonce security, and that the server is properly
configured to support nonces in the network environment.
