The plugin validates every node in the "sitemap" to make sure it has the properties required by the plugin. While the type field of a sitemap node is validated to be a string, the length of the string isn't checked. This means that an empty string ("") would pass validation, that might cause all kinds of weird errors.
Note that the typePrefix also has effect on the final name of a type. When a type prefix is configured, types with an empty name might be treated as if their type name is just the prefix. E.g. a prefix of Umbraco and an empty type name would result in "Umbraco". This is even more difficult to debug.
