JS-YAML: missed comma between flow collection entries

[joaocarreiras]

Hi,

Following the tutorial in http://apiworkbench.com/docs/ for Api-workbench, section "Extracting the Library". I'm getting the following error "JS-YAML: missed comma between flow collection entries at line" in several lines (which I've put in bold)
My RAML files are
#%RAML 1.0
title: Pet Shop
version: v1
baseUri: /petshop
mediaType:

• application/json
  description: API example designed with API Workbench

uses:
NewLibrary: NewLibrary.raml
types:
Mammal:
type: NewLibrary.Pet
Bird:
type: NewLibrary.Pet
properties:
wingLength: number

/pets:
type: { NewLibrary.Collection: {item : NewLibrary.Pet }
get:
queryParameters:
petKind:
enum: [bird, mammal]
is: [NewLibrary.FilterableByPrice]
/{id}:
type: { NewLibrary.Member: {item : NewLibrary.Pet} }

/birds:
type: { NewLibrary.Collection: {item: Bird} }
get:
is: NewLibrary.FilterableByPrice
/{id}:
type: { NewLibrary.Member: {item : Bird} }

/mammals:
type: { NewLibrary.Collection: {item: Mammal} }
get:
is: NewLibrary.FilterableByPrice
/{id}:
type: { NewLibrary.Member: {item : Mammal} }

The "NewLibrary.raml" is below
#%RAML 1.0 Library
types:
Pet:
#discriminator: kind
properties:
name: string
kind: string
price: number
color:
enum:
- White

price: 100
color: Black

application/json:

application/json:

traits:

I've no idea why this error appears. I've compared it with the tutorial and can't find the difference

I forgot to mention my machine is running Windows 10

@joaocarreiras YAML is a whitespace sensitive language, and as you made your post there is no indentation (which I am guessing is not correct) and we cannot tell what your input is. Could edit and correct your post? You will probably want to use fenced code blocks.

I can confirm I get the error on this use-case:

const s = `key: [ Some text here
and another line here ]`
safeLoad(s)
// throws YAMLException: missed comma between flow collection entries at line 2, column 1

Although the online YAML parser parses this as:

{
  "key": [
    "Some text here and another line here"
  ]
}

Showing failure against js-yaml: http://nodeca.github.io/js-yaml/#yaml=a2V5OiBbIFNvbWUgdGV4dCBoZXJlCmFuZCBhbm90aGVyIGxpbmUgaGVyZSBd

Since the issue still exists in js-yaml, you might wish to report the issue there. Once it is fixed here, the fix could be ported to this library.
