Doesn't support external file references

[rajpaulbagga]

Would love to make use of this plugin. But...

Detailed description

It fails when the spec file has references to other files. I get a 404 in the window looking for the child file using its absolute path.

Context

OpenAPI specs may be split across multiple files with references to other files to fill in, for example, schema.
E.g. something like this swagger 2.0 yaml snippet:

path:
  /invitations:
    get:
      consumes:
        - application/json
      produces:
        - application/json
      parameters:
        - name: "email"
          in: query
          type: string
          description: "Email address of invitee"
          required: false
      responses:
        200:
          description: "Matching Invitations"
          schema:
            $ref: 'some-other-openapi-schema-files.json'

This would result in a failure like this when switching to the Redoc view:

Something went wrong...
