Hi,
the documentation for that operation seems a bit off, I open an issue
for this:
https://github.com/GeoWebCache/geowebcache/issues/785
As far I can tell this is the correct way of truncating a layer via GWC
REST API:
    curl -v -u admin:geoserver --request POST \
      --url http://localhost:8080/geoserver/gwc/rest/masstruncate     \
      --header 'content-type: text/xml' \
      --data
    '<truncateLayer><layerName>BASE:LAND</layerName></truncateLayer>'
Anyway, to avoid the error you are getting you need to explicitly use
text\xml for the content type.
Hope it helps,
Nuno Oliveira
