Public bug reported:

The Kilo Keystone release dropped support for requests with XML bodies,
but included shims to (presumably) prevent existing configs from
breaking. This works as desired for XmlBodyMiddleware, but not
XmlBodyMiddlewareV2 and XmlBodyMiddlewareV3. As a result, all client
requests to a pipeline with either of those filters will receive a 500
response and the server's logs look like
