在文件中使用中继突变的问题

Question

I have an issue using File Mutation with Relay. I am trying to create a mutation using getFiles()

Relay.Store.commitUpdate(
  new AddOrderMutation({userId: userId, medications: OrderInputTypeMedication,
    userAddressId:userAddressId,files:files}),
  {
    onSuccess: (response) =>  OnResponseSuccess(response),
    onFailure: (transaction,e) => console.log('transaction',transaction.getError(),'e',e),
  },
);

}

I always get an error that said transaction TypeError: Network request failed at XMLHttpRequest.xhr.onerror (D:\\ReactNative\\MedexApp\\node_modules\\react-native\\node_modules\\whatwg-fetch\\fetch.js:436) although all other requests are working good. also the same mutation is sent correctly without attaching any files. this is the array of files ["1489322712989.jpg":{filename:"1489322712989.jpg" uri:"file:///storage/emulated/0/Pictures/1489322712989.jpg"}] and It never sends the request through fiddler or caught in the webservice

Answer 1

I wasn't adding to the Files Object (type: 'image/jpg'), so the file Object should be as follows:

file ={
         uri: this.state.image.uri,
         name: this.state.image.name,
         type:'image/jpg'
       };
