Controller fails to process a PATCH request where
- target is set to a single forward slash (/)
- Target data node resource of the URI is not a top-level node
- Data is encoded in JSON
For example, the following PATCH request to update the configuration of NETCONF topology node
PATCH /rests/data/network-topology:network-topology/topology=topology-netconf/node=ncserver
Accept: application/yang-data+json
Content-Type: application/yang-patch+json

Equivalent PATCH request in XML works without any error:

RFC 8072 Section 2.4 Target Data Node
If the target resource specified in the request URI identifies a
datastore resource, then the path string in the "target" leaf is
treated as an absolute path expression identifying the target data
node for the corresponding edit. The first node specified in the
"target" leaf is a top-level data node defined within a YANG module.
The "target" leaf MUST NOT contain a single forward slash ("/"),
since this would identify the datastore resource, not a data
resource.If the target resource specified in the request URI identifies a
configuration data resource, then the path string in the "target"
leaf is treated as a relative path expression. The first node
specified in the "target" leaf is a child configuration data node of
the data node associated with the target resource. If the "target"
leaf contains a single forward slash ("/"), then the target data node
is the target resource data node.
