Wrong filename provides to downloaded file if URI has no filename at the end.

If file's URI has no filename and(or) extension at the end (e.g. https://.../api/reference/financial, or https://.../api/files/ddf57hghm54s64s...), the downloaded file won't be saved properly. It won't have a real filename, but smth like "downloadfile.bin" on android and last part of save-dir on IOS (e.g save-dir === "/app/files" -> filename === "files").

That seems I have to set save-dir with a real filename at the end ("app/files/filename.ext"). But how can I do this if I didn't fetch the file yet?! :( If the URI-to-file includes a filename, file saves correctly on android, but still not (like described above) on IOS..

I just don't know how to resolve this.. :(

My code:

const fileURI = `https://.../files/sasf6s7dbd8fg90fdbetn`;
const saveToPath = `${dwnldFileDirs.DownloadDir}/app/files`;

RNFetchBlob
  .config({
    path: saveToPath,
    fileCache: true,
    addAndroidDownloads : {
      useDownloadManager : true,
      notification : true,
      mediaScannable: true,
      description : '',
      mime: '/'
    }
  })
  .fetch('GET', fileURI)
  .then((res) => {...})
