Downloaded file with status 200 but file doesn't exist in Android 10 emulator

[olcayertas]

I am downloading a XLSX file on an Android 10 emulator (Pixel 3a API 29). Operation ends with HTTP status code 200. Here is the response headers:

{
  "Server": "Gozen Web Server",
  "Accept-Ranges": "bytes",
  "Content-Disposition": "attachment; filename=2019_11_04_05_11_2019_sali_Iga_saatler_5dc0466c121e1.xlsx; filename*=utf-8''2019_11_04_05_11_2019_sali_%C4%B0ga_saatler_5dc0466c121e1.xlsx",
  "Last-Modified": "Mon, 04 Nov 2019 15:40:27 GMT",
  "Date": "Tue, 05 Nov 2019 07:26:32 GMT",
  "Cache-Control": "public",
  "Connection": "close",
  "Content-Length": "88156",
  "Content-Type": "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
}

Here ismy download code:

function download(url, completion: (response: Response) => {}) {

  getTokenAsync().then(value => {
    if (value === null) {
      showMessage("Failed to get token!", null);
      return;
    }
    let headers = { Authorization: "Bearer " + value };
    let options = { fileCache: true };
    console.info("Downloading: " + url);
    RNFetchBlob.config(options).fetch("GET", url, headers).then(response => {
      let status = response.info().status;
      console.log(status + " " + url);
      if (status === 200) {
        let dir = Platform.OS === "ios" ?
          RNFetchBlob.fs.dirs.DocumentDir :
          RNFetchBlob.fs.dirs.DownloadDir;
        let sourcePath = response.path();
        let destinationPath = dir + "/" + getFileNameFromResponseAndUrl(response, url);
        RNFetchBlob.fs.exists(sourcePath).then(value => {
          console.log("download: Source path " + value);
          RNFetchBlob.fs.exists(destinationPath).then(value => {
            if (value) {
              RNFetchBlob.fs.unlink(destinationPath).then(() => {
                moveAndOpen(response.path(), destinationPath);
              });
            } else {
              moveAndOpen(response.path(), destinationPath);
            }
          });
        }).catch(reason => {
          console.log(reason);
        });
      } else if (status === 404) {
        showMessage("Dosya bulunamadı!", null);
      } else if (status > 499 && status < 600) {
        showMessage("Sunucu hatası!", null);
      } else {
        showMessage("Dosya indirilemedi! " + status);
      }
      completion(response);
    }).catch(reason => {
      //console.error(JSON.stringify(reason, null, 2));
      showMessage(reason);
      completion(null);
    });
  });
}

File seem to be download to this path: /data/user/0/com.gozensahamobile/files/RNFetchBlobTmp_1h7oxinvsiltpzzeb7khc and RNFetchBlob.fs.exists function returns true but when I look at the application's files folder with file explorer of emulator there is no file and my move code fails:

export function moveAndOpen(source, destination) {
  RNFetchBlob.fs.mv(source, destination).then(() => {
    open(destination);
  }).catch(reason => {
    console.error("moveAndOpen: " + reason);
  });
}

This code was working good before. Can anyone have the same problem?

@olcayertas have you solved the issue? I am facing similar issue with version 0.12.0, RN version 0.62.0. I am getting file exists true but file is not visible in file explorer
