Android response info error

[MuratAkbaba006]

Hello, in android app when I fetched a file, respInfo don't includes status etc. information.
its seems like this.
"respInfo": {"rnfbEncode": "path"}

[RonRadtke]

Which version are you using? And please a little snippet of your code so we know ehst exactly you're doing

[alelaru]

@MuratAkbaba006 you do not understand it because it is an error of the package.

"react-native": "0.71.4",
"react-native-blob-util": "0.18.3",
"react": "18.2.0",

@RonRadtke the problem is that when installing the packages and running them into the android device sometimes .fetch() will return the correct object with all the information inside and sometimes it will return the object @MuratAkbaba006 shows.

In my case i make a post request to get some data and it will download the file properly but the object res.info() its empty and i also cannot the progress wont log the progress as if it was not called, maybe it is the same error. Ive reinstalled the package and by chance sometimes it works and sometimes it doesn't this error was found previously as res.info() returns undefined

My call looks like this, nothing complicated:

       await ReactNativeBlobUtil.config({
      path,
      fileCache: true,
    })
      .fetch(
        'POST',
        ....
      )
      .progress({ count: 25 }, (received, total) => {
        console.log('\n -------- > progress', {
          received,
          total,
        });
      })
      .then(res => {
        attachmentsUpdated = true;
        if (res.info().status === 200) {
          console.log(`Sound file name: ${originalFilename} downloaded`);
        } else {
          console.log('Unknowkn', res.info().status);
        }
      });

@alelaru are you able to reproduce this behavior? Does in addition occour any error?

[MuratAkbaba006]

@RonRadtke I tried 0.17.2, 0.17.3, 0.18.3 versions. all of them same result.

here is my code;

I am getting the same issue on iOS in release builds on file upload.

The response doesn't include text or status and no progress. Just this:

{"rnfbEncode": "utf8"}

Here's the upload code, this works in debug but not in release build:

let request = RNFetchBlob.config({
      IOSBackgroundTask: !globalThis["IS_SHARE_EXTENSION"]
    })
      .fetch(
        "PUT",
        uploadUrl,
        {
          "content-type": ""
        },
        RNFetchBlob.wrap(uploadFilePath)
      )
      .uploadProgress((sent, total) => {
        useAttachmentStore
          .getState()
          .setProgress(sent, total, filename, 0, "upload");
        DatabaseLogger.info(`uploading file: ${sent}/${total}`);
      });
    cancelToken.cancel = request.cancel;
    let response = await request;

    let status = response.info().status;
    let text = await response.text();

The request does get sent to the server because if i disable internet, i get a proper error thrown. I have confirmed that the file exists at the upload path.

Version: 0.17.3

Edit: This is inconsistent. doesn't happen always.

Edit: Stepping through the code, I found out that req is nil in sendRequest on iOS:

[MuratAkbaba006]

Additionally, if the file does not exist or there is some other error on backend side. catch block and timeout duration doesn't work. @RonRadtke

I was on v0.17.3. Upgrading to 0.18.3 has fixed the issue for me on iOS. As i tracked it down DeviceEventEmitter not receiving any events. The 0.18.3 replaces that with NativeEventEmitter which fixes the problem. As you are facing the issue on android, the probable cause can be something similar because:

If the below event doesn't fire before fetchBlob method callback is called, the respInfo includes just rnfbEncode:"type of encoding"

stateEvent = eventEmitter.addListener('ReactNativeBlobUtilState', (e) => {
            if (typeof e === 'string') e = JSON.parse(e);
            if (e.taskId === taskId)
                respInfo = e;
            promise.onStateChange && promise.onStateChange(e);
        });

And just to be 100% sure I have added below code to ensure I get the response status code in any case the events don't fire:

and made slight change to fetch.js:

if (respInfo.status === undefined || respInfo.status === null) {
                    respInfo.status = resp.status
                }
                resolve(new FetchBlobResponse(taskId, respInfo, data));

If it's still happening on android, my guess is event is not fired on time or not fired at all during fetch request sometimes.

Here's the final patch for android & ios I am using now just to be safe:

Hello, in android app when I fetched a file, respInfo don't includes status etc. information. its seems like this. "respInfo": {"rnfbEncode": "path"}

I tried 0.17.1, 0.17.3, 0.18.3 versions. but got same issue.
have you solved it, pls help me :(

[RonRadtke]

Thank you for the patch I will take a look at and see if ai can get it integrated soon

Hello, I'm still facing the issue with version 0.19.4. Unable to retrieve the response code or status code or the error messages or the success messages from the responses while downloading the PDF files.
