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

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.
