Error code 1 cordova plugin file transfer android

I have a problem on cordova (android), when I try to download a file (a .zip exactly), It always occured a error code 1. The url downloads well on my computer. Here is the code :

    let fileTransfer = new FileTransfer();
      url = encodeURI(url);

      fileTransfer.download(
        url,
        cordova.file.externalApplicationStorageDirectory,
        function(entry) {
          console.log('download complete: ' + entry.toURL());
        },
        function(error) {
          console.log('download error source ' + error.source);
          console.log('download error target ' + error.target);
          console.log('upload error code is ' + error.code);
        });

Thanks

The error was that I forgot to specify the name of the file when it will be downloaded on the device, I didn’t know I had to specify that. So here is the corrected code (modifications at lign 6) :

  let fileTransfer = new FileTransfer();
  url = encodeURI(url);

  fileTransfer.download(
    url,
    cordova.file.externalApplicationStorageDirectory+'whatever.png',
    function(entry) {
      console.log('download complete: ' + entry.toURL());
    },
    function(error) {
      console.log('download error source ' + error.source);
      console.log('download error target ' + error.target);
      console.log('upload error code is ' + error.code);
    });
