[YANGTOOLS-804] Netconf response payload fails to render in JSON, only XML works in RestConf response

Sun, 10 Apr 2022 18:36:01 +0000

Version: Boron-SR3.

Restconf call to Netconf-mounted router to fetch some data with Accept: json header results in severely truncated response payload.

The same call with Accept: xml header results in the entire payload correctly rendered.

Setting TRACE options for netconf within karaf shows the netconf data is indeed intact in the router's RPC response.

{set TRACE org.opendaylight.netconf.sal.connect.netconf, set TRACE org.opendaylight.netconf}

(also in karaf log) A suspicious (or not) WARN about leading LF (0a) character (which can be seen in the NetconfXMLToMessageDecoder raw netconf response payload).
