Explanation

The correct Content-Type header for NETCONF over RESTCONF when using JSON-encoded YANG data is 'application/vnd.yang.data+json'. This follows the RFC 8040 RESTCONF standard, where the media type uses the format 'application/vnd.yang.data+' followed by the encoding type (json or xml). The '+json' suffix explicitly specifies that the payload is JSON-encoded YANG data.
