io.netty.handler.codec.http.multipart.HttpPostRequestEncoder$ErrorDataEncoderException：java.io.FileNotFoundException

问：

你能帮我解决这个问题吗（我遇到错误）：

 Data:
    {
     "file":"bird.jpeg"
      }

    My Graphql query:
    mutation UpdateProfilePicture ($file: Upload!) {
        singleUpload(file: $file){
        done
    }
   }

功能文件：

Feature: get parent players

    Background:
    * url baseUrl
    Scenario: get parent players details

    * def result = call read(loginPath)
    * def accessToken = result.accessToken
    * print "Access Token : ", accessToken
    And header Authorization = 'Bearer ' + accessToken

    Given def query = read(gqlBase +'updateProfilePicture.gql')
    And request { query: '#(query)'}
    * multipart file file = {read:'bird.jpeg', filename:'bird.jpeg',Content-type:'image/jpeg'}
    When method post
    Then status 200
    * print 'response: ', response.data

当我尝试上传图片时，出现以下错误：
