inso CLI generates invalid config if protocol is missing from server URL

[reitzig]

Expected Behavior

Output:

_format_version: "1.1"
services:
  - name: Some_Service
    protocol: http
    host: foo.bar.svc.cluster.local
    port: 80
    path: /
    plugins: []
    routes:
      - tags:
          &a1
          - OAS3_import
          - OAS3file_openapi_mwe.yaml
        name: Some_Service-getHello
        methods:
          - GET
        paths:
          - /hello$
        strip_path: false
    tags: *a1

or a descriptive error.

Actual Behavior

Output:

_format_version: "1.1"
services:
  - name: Some_Service
    protocol: http
    host: localhost
    port: 80
    path: /foo.bar.svc.cluster.local
    plugins: []
    routes:
      - tags:
          &a1
          - OAS3_import
          - OAS3file_openapi_mwe.yaml
        name: Some_Service-getHello
        methods:
          - GET
        paths:
          - /hello$
        strip_path: false
    tags: *a1

Note services[0].host and services[0].path.

While inso guesses/defaults to HTTP and port 80, parsing the server path seems to get tripped up by the lack of protocol.

Reproduction Steps

1. Create file openapi_mwe.yaml with content:

   
   openapi: 3.0.2
   info:
   title: Some Service
   version: "@project.version@"
   contact:
   name: Me
   description: bar

servers:

• url: 'foo.bar.svc.cluster.local'

tags:

• name: 'greeter' description: 'you should have one'

paths: /hello: get: operationId: getHello description: "Says hello" tags:

• greeter responses: '200': description: OK

2. FWIW, run `inso lint spec openapi_mwe.yaml` -- OK
3. Run `inso generate config -t declarative openapi_mwe.yaml`

While inso guesses/defaults to HTTP and port 80

FWIW, a silent yet insecure default may not be ideal. I'd expect a straight-up error (no default) or at least a linter warning (if not error).
