yang-express's Issues

openapi: Cannot read property 'nodes' of undefined

Understand that this is still under development. I am reporting this for tracking -

Running the yang-express/example petstore, I get the following error -

bash-4.3$ curl localhost:5000/openapi.spec
{
  "error": {
    "message": "Cannot read property 'nodes' of undefined"
  }
}bash-4.3$

Server Log -

TypeError: Cannot read property 'nodes' of undefined
  at Function.restjson.paths (.../yang-express/lib/restjson.js:138:18)
  at .../yang-express/lib/openapi.js:57:27

I am using following versions of dependencies :
"yang-express": "^0.3.9",
"yang-js": "^0.15.16",

The latest changes to yang-js project may have broken it.

Facing errors while trying to run yang-express

Hi There,

I was trying to integrate a yang-parser in an Angular (v9) application, for which I resorted to using yang-express. After installing I ran below command:

yang-express src/app/yangs/demo.yang

It yields below output, the issue it's pointing to is in the yang-express file inside the bin folder.

WARNING: No configurations found in configuration directory:/home/yang-demo/config
WARNING: To disable this warning set SUPPRESS_NO_CONFIG_WARNING in the environment.
/usr/local/lib/node_modules/yang-express/bin/yang-express:37
var schema = require('..').bind({
                           ^

I am running node version 10.19.0 and npm 6.14.4.
Please provide your thoughts.

TypeError: discover is not a function

if you run " git clone https://github.com/corenova/yang-express;" then run "cd yang-express" then run "npm install"

and finally you run "yang-express example/example-petstore.yang" or "npm run example:petstore"

you get this error message:

Strange POST behavior on nested lists

Notice the strange behavior on nested list structure...

Yang Model

bash-4.3$ cat example/petstore.yang

    leaf id   { type uint64; mandatory true; }
    leaf name { type string; mandatory true; }
    leaf tag  { type string; }
  }
  list pet {
    key "id";
    uses Pet;

    list childpet {
      key "id";
      uses Pet;

      list grandchildpet {
        key "id";
        uses Pet;
      }
    }
  }

Any documentation on how to use its capabilities/features ?

Any documentation providing how to use the hot deployment of YANG modules in a running instance will be helpful. Documentation in general can be helpful here.
