Retrieving VNF-INFO via NSO JSON-RPC API

Hi Experts,

I have NSO 5.2.1.2 installed with NFVO 4.2.

With NSO JSON-RPC calls, I was able to retrieve info from some service points, but not others. See below "good" ones in green and "bad" ones in red:

"service_points": {
"/nfv:nfv/cisco-nfvo:internal/sol3-deployment": "/nfv:nfv/cisco-nfvo:internal/sol3-deployment",
"/nfv:nfv/cisco-nfvo:internal/netconf-deployment": "/nfv:nfv/cisco-nfvo:internal/netconf-deployment",
"/nfv:nfv/cisco-nfvo:ns-info": "/nfv:nfv/cisco-nfvo:ns-info",
"/nfv:nfv/cisco-nfvo:onboarding/netconf/volume": "/nfv:nfv/cisco-nfvo:onboarding/netconf/volume",
"/nfv:nfv/cisco-nfvo:onboarding/netconf/image": "/nfv:nfv/cisco-nfvo:onboarding/netconf/image",
"/nfv:nfv/cisco-nfvo:onboarding/netconf/flavour": "/nfv:nfv/cisco-nfvo:onboarding/netconf/flavour",
"/nfv:nfv/cisco-nfvo:vnf-info": "/nfv:nfv/cisco-nfvo:vnf-info"
}

 

Command below took the last "vnf-info" service point as an example to show what "bad" means:

$ curl -i -X POST -d '{"jsonrpc":"2.0","id":4,"method":"get_schema","params":{"th":1,"path":"/nfv:nfv/cisco-nfvo:vnf-info","evaluate_when_entries":true,"insert_values":true,"levels":-1}}' -H 'Content-Type: application/json' --cookie 'sessionid_8080=sess4oBSe/I4JA63/HLSchgcxA==;' http://192.168.25.15:8080/jsonrpc

HTTP/1.1 200 OK

{"jsonrpc":"2.0","error":{"type":"rpc.internal_error","code":-32603,"message":"Internal error (reason unknown)","internal":"webui_session_server723"},"id":4}

 

No clue what's wrong with the message, I went to NSO log directory and did a "tail -f *" when sending the command above again. Here is the screen:

Anyone able to interpret what went wrong?

 

Thanks

I would recommend you to open a TAC ticket because "Internal error (reason unknown)" is typically a sign that something is wrong beyond where a forum can help you.
