Error: Network error: Network request failed in my React-Native project

[gHashTag]

Why do I get this error?
Error: Network error: Network request failed

My store

export const client = new ApolloClient({
  link: createUploadLink({ uri: 'http://localhost:3030/graphql' }),
  cache: new InMemoryCache()
})
const middlewares = [client.middleware(), thunk]
export const store = createStore(
  reducers(client),
  undefined,
  composeWithDevTools(applyMiddleware(...middlewares)),
)

My backend here

My mutation:

export default gql`
  mutation($file: Upload!) {
    uploadFile(file: $file)
  }
`

My action:

  _onShowSignupPress = async () => {
    const { profilePhotoUri } = this.state
    const file = new ReactNativeFile({
      uri: profilePhotoUri,
      type: 'image/jpeg',
      name: 'photo.jpg'
    })
    const response = await this.props.mutate({ variables: { file } })
    console.log(response)
  }

In the Apollo Client 2.0 version they removed the internal dependency on redux, so i won't be able to using the client.middleware anymore.
