React Native 0.62.* [TypeError: Network request failed] on file upload

[abumostafa]

Please provide all the information requested. Issues that do not follow this format are likely to stall.

Description

After upgrading from 0.61.4 to 0.62.0 the app will not upload files anymore from Android (all other requests are working fine)

React Native version:

0.62.0

Steps To Reproduce

1. Install a fresh ReactNative app via CLI
2. Upload a file to the emulator
3. Try to upload a file using fetch

import Picker from "react-native-image-picker"
import {request, PERMISSIONS, RESULTS} from 'react-native-permissions';

class App extends React.Component {

  async componentDidMount() {

    try {
      await request(PERMISSIONS.ANDROID.WRITE_EXTERNAL_STORAGE)
      await Picker.launchImageLibrary({noData: true}, async (file) => {
        try {
           const body = new FormData()
           body.append("file", { type: file.type, size: file.fileSize, uri: `file://${file.path}`, name: file.fileName })
           const headers = { "content-type": "multipart/form-data", "accept": "application/json" }

          const req = await fetch("ANY_SERVER/upload/image", {
            method: "POST",
            headers,
            body
          })
          console.log(req.status)
        }  catch (e) {
          console.log(e)
        }
      })
    } catch (e) {
      console.log(e)
    }
  }

  render(){
    return <View/>
  }
}

Expected Results

The request should reach the server to upload the file

Same problem here!

Same problem !! I am stuck on this issue from last 2 days! Searched almost everything..

You need to add this uesCleartextTraffic="true" to the AndroidManifest.xml file found inside the dir android/app/src/main/AndroidManifest.xml

    <application
      ...
      android:usesCleartextTraffic="true">

According to docs

When the attribute is set to "false", platform components (for example, HTTP and FTP stacks, DownloadManager, and MediaPlayer) will refuse the app's requests to use cleartext traffic. Third-party libraries are strongly encouraged to honor this setting as well. The key reason for avoiding cleartext traffic is the lack of confidentiality, authenticity, and protections against tampering; a network attacker can eavesdrop on transmitted data and also modify it without being detected.

I have tried it already. This is used when you are making request to a http server, but my server is running on https. It was running perfectly before upgrading to 0.62.
Something is wrong.

[adityamohta]

All other requests are working perfectly. Only file uploads are not working anymore.

[HaidarZ]

All other requests are working perfectly. Only file uploads are not working anymore.

I faced too many issues when I tried upgrading to 0.62 even though I created a new app and moved my code into it. I rolled back to 0.61.5 till it gets stable :/

[MateuszRostkowski]

I am facing the same issue, for RN 0.62.0 and 0.62.1 throws this error: Network request filed.
All requests work except for the image post

[adityamohta]

I moved back to 0.61.5 :( No other choice left for now. If anyone needs help in downgrading to 0.61.5, refer to react-native-upgrade-helper.

[preko96]

Same happens here!

[alfianwahid]

I faced same issue, it happens in Android, but works well in IOS.
I guess this issue about Flipper Network.

For while, I commented
initializeFlipper(this, getReactNativeHost().getReactInstanceManager())

in this file
/android/app/src/main/java/com/{your_project}/MainApplication.java

[trglairnarra]

This issue occurs also on my end, and guess what it is only occurring in debug mode. Tried building in internalRelease and it works fine. I guess it is because of the auto/fast reload in debug mode which applies some flipper communication which seems to be related in this issue..

Another issue here is that there is no error in android logcat.. I've also spent some days researching how to fix this issue still no luck.

[abumostafa]

Whoever is still struggling with this issue. it's happening because of Flipper network plugin.
I disabled it and things work just fine.

My workaround to make this work is commenting out line number 43

38      NetworkFlipperPlugin networkFlipperPlugin = new NetworkFlipperPlugin();
39      NetworkingModule.setCustomClientBuilder(
40          new NetworkingModule.CustomClientBuilder() {
41            @Override
42            public void apply(OkHttpClient.Builder builder) {
43      //        builder.addNetworkInterceptor(new FlipperOkhttpInterceptor(networkFlipperPlugin));
44            }
45          });
46      client.addPlugin(networkFlipperPlugin);

Thanks for the issue @abumostafa. Does this occur in a fresh React Native template out of the box? If so this should be looked at otherwise feel free to close it.

@safaiyeh
I can confirm. It's still happening in the latest fresh react native template 0.62.1

[ThangNguyen1998]

RN Version - 0.63.4
Flipper - 0.54.0.
I have facing same issue. I have changed Flipper version to 0.41.0. Now issue fixed. Thanks

not working in my case.

Hi , If you upload image set type : 'image/jpeg',

Hey @abumostafa, What in the case of managed workflow like Expo where there is no access to native project files, what could be the possible solution in that case ?

[vinod-bluebash]

This solution worked for me:

https://forums.expo.io/t/network-request-failed-while-uploading-image-to-server/30737/5

I've got it please refer this resolution in case of Expo's managed workflow.

[AmirDiafi]

This issue solved in react-native 0.63.3+

[vinod-bluebash]

This issue solved in react-native 0.63.3+

Ok, So I feel the point is made clear that the issue is while trying to send invalid file validated attributes like invalid file uri, type or in case some missing required data attributes like name, while the issue being resolved.

[mirfanahmed]

Hello. I am facing a problem from past 2 days in android that whenever I try to hit an api through axios by simply sending a formdata I get a network error. I have updated to expo sdk 41 and react native version 0.63.3 but it still it gives me this error. I need urgent help.

[kylanhurt]

Still having same issues in RN 64.1

[itajenglish]

@mirfanahmed and @kylanhurt I fixed this issue by hard coding the file type extention. Take a look at the uriParts variable and fileType variable. Let me know if this works for you.

  const createFormData = (photo) => {
    const data = new FormData();
    const uriParts = photo.uri.split('.');
    const fileType = uriParts[uriParts.length - 1];

    data.append('image', {
      name: 'profilePic',
      type: `image/${fileType}`,
      uri: Platform.OS === 'ios' ? photo.uri.replace('file://', '') : photo.uri,
    });

    return data;
  };

This works for me

[quachdev]

I am getting this issue now on 0.64.2. Uninstalling Flipper is not working either. Anytime I make a network request (not just file upload) I get TypeError: Network request failed on Android.

iOS works fine.

Edit: Managed to isolate the issue to a dependency that we are using.

[itajenglish]

@quachdev Try adb reverse tcp:8081 tcp:8081

[quachdev]

adb reverse tcp:8081 tcp:8081

Tried and no luck. Same result. Have tried to invalidate cache and restart as well on Android Studio.

[ak2403]

Same issue exists. The API call is working in a real device, but not in the emulator.

Now, my concern is, Should I worry that it doesn't work on emulator? It will be good if someone can answer this question, so that I can work with the real device until this issue is sorted out.

[3KINGZ]

I'm facing this issue i've literally tried everything
"react-native": "0.64.1",

[tohshine]

same issue I have tried all the solutions but doesn't work
"react-native": "0.64.1",

while the file is part of the append throws a network error

` let body = new FormData()
body.append('location', 'GOOGLE_DRIVE')
body.append('docType', 'MEANS_OF_IDENTIFICATION')
body.append('file', { ...attachment.file })
const data = await axios.post('/file/api/v1/storage/folder/file', body, config, {
onUploadProgress: (progress) => {
const { loaded, total } = progress;
const percentagProgress = Math.floor((loaded / total) * 100);

                /* dispatching peercentage */
                dispatch(fileUploadProgress(attachment.id, percentagProgress));
            },
        });
        /* dispatch success upload */
        dispatch(successFileUpload(attachment.id));
        console.log('success data', data);`

[itajenglish]

Can you guys update your comments with the code you're trying to execute.

[thanhhai16]

Can you guys please help me, I'm struggling with this, I tried all the way, but my code still sends [object Object] to server?
This was worked well in past at 0.59 .
Please help me

What file is this logic in? Is it in the file with the component that's selecting the image from the file system or a separate file? @tohshine

Update the comment with your RN code @thanhhai16

[ionbaratol]

react native 0.64
✅ adding the content type in headers solved the issue for me.

fetch(urls[i], {
              method: 'put',
              headers: {'Content-Type': `${contentType}; charset=utf-8`},
              body: binaryFile,
            })

[FratilaRuxandra]

Check first if your upload works with very small files ( for example, instead of uploading a video, upload a gif ). In my case, any file over 1 MB would return "TypeError: Network request failed".

After many attemps, it turns out that the problem was caused by me using localtunnel, which limited my maximum file size.

[FoolCoder]

i getting this in RN 0.64 , while i individually upload image or video but when i upload with image and video text it works fine

[princefishthrower]

@abumostafa - legend.

Two weeks. Two weeks of scratching my head why file uploads were working absolutely fine in iOS, but wouldn't work in Android. Commenting a single line in a dev-only relevant file makes it work.

Incredible.

I love my life.

[skywalker2013]

i face same issue in RN 0.65.1. why close the issue? have any solution?

@princefishthrower - @abumostafa solution works for Android, how did you manage to resolve it for iOS? We are also facing this issue in iOS

[princefishthrower]

@juggernauts In my case the file upload endpoint (sendbird chat profile upload if it helps) was working on iOS well before I did this "fix". To help further, I use the react-native-image-crop-picker with iOS and send the following fields in my 'file':

const result = await ImagePicker.openPicker(imagePickerOptions);
const file = {
          uri: result.path,
          type: result.mime,
          name: "anyStringHoweveryouWantToDefineTheFileName",
};

Also, I had a huge typo in my comment, this fixed file uploads for Android - iOS was working the whole time. Sorry for any confusion that may have caused! The good news is if you have Android working, iOS should be easier - at least that's how it was in my case.
