REST API - Swagger - Don't understand why “Not a valid parameter definition”

Question

I face issue with my swagger file :

swagger: '2.0'
paths:
  /currencies:
    get:
      responses:
        '200':
          description: ''
      summary: 'list currencies summary'
      x-auth-type: None
      x-throttling-tier: Unlimited
      produces:
        - application/json
      description: 'list currencies description'
  '/currencies/{currencieId}':
    get:
      responses:
        '200':
          description: ''
      description: 'Single currency description'
      parameters:
        - name: currencieId
          in: path
          allowMultiple: false
          required: true
          type: string
          description: 'paramter description'
      summary: 'Single currency'
      x-auth-type: None
      x-throttling-tier: Unlimited
      produces:
        - application/json
info:
  title: MDM
  version: v1

Here is my issue :

✖ Swagger Error Not a valid parameter definition Jump to line 20 Details Object code: "ONE_OF_MISSING" params: Array [0] message: "Not a valid parameter definition" path: Array [5] 0: "paths" 1: "/currencies/{currencieId}" 2: "get" 3: "parameters" 4: "0" schemaId: " http://swagger.io/v2/schema.json# " inner: Array [2] level: 900 type: "Swagger Error" description: "Not a valid parameter definition" lineNumber: 20

Issue in swagger editor

I am a bit lost with that ....

Thanks for your help.

Answer 1

Remove allowMultiple: false from the definition of the currencieId parameter. That eliminates the error.

The allowMultiple keyword does not exist in the OpenAPI (fka Swagger) Specification 2.0 . It was used in v1.2 , but in 2.0 it was replaced with type: array and collectionFormat .

Answer 2

allowMultiple：假不正确
